1. Introduction to Python
Python is a high- A programming language that’s easy to read and write, and can be used in many different ways This thing can handle different coding styles, so it’s great for all sorts of projects It’s easy to read and big community make it one of the most popular languages nowadays
2. What is PEP 8?
PEP 8 is the official guide that sets the coding standards for Python It aids developers in crafting tidier and more uniform code fro various projects Adhering to PEP 8 makes Python code easier to read, maintain, and work on with others
3. What does “interpreted language” mean about Python?.
Python runs the code one line at a time, not compiling it all together This simplifies the debugging process adn speeds up development for coders But it might run a bit slower than compiled languages because it’s executed in real-time
4. What is a Python Module?
A module is a file with Python code, like functions, classes, or variables Tihs lets you reuse code and keep your programs tidy by breaking things down Modules can be built-in, custom-made, or third-party packages
5. What is a Python Package?
A package is basically a bunch of modules tucked away in a folder that has an __init__.py file It’s a neat way to keep all related modules in one tidy folder Packages help make big apps easier to handle and use again
6. What is a Function in Python?
A function is a piece of code you can use over and over to do a certain job It’s a good practice to prevent repeating code and keeps the program neat and tidy Functions are made with the def keyword and a name for the function
7. What is a Lambda Function?
A lambda function is essentially a tiny and nameless function that is produced with the help of the lambda keyword. It is mainly utilized for quick and trivial actions – no extensive function definition is needed. Moreover, the use of lambda functions in sorting, filtering, and mapping operations is considered the best and foremost option.
8. What is a List in Python?
A list is basically a bunch of items you can tweak and line up in any order, all snug in those square brackets.You can toss in, pull out, or swap things whenever you feel like it.Lists are super useful in coding since they can cradle all kinds of data types
9. What is a Tuple?
A tuple can be visualized as a tidy little bundle of elements that are immutable and keep an order, all wrapped in parentheses. Once you have it, you cannot alter the values inside. They are excellent for controlling your data and maintaining proper focus on it.
10. What is a Dictionary?
A dictionary keeps info organized with key-value combos adn makes finding things quick and easy It’s all over the place, can change, and wrapped in curly braces People often turn to dictionaries to give data unique tags
11. What is a Set?
A set in Python is like a bag that doesn’t care about the order of things and only keeps each item once It nixes the same stuff and does membership checks quick Sets come in handy for doing math stuff like combining things or finding common elements
12. What is OOP in Python?
OOP (Object- Object-oriented programming is a way of writing code that organizes it using objects and classes It’s like giving real-world stuff its own personality and quirks Python really gets object-oriented programming with inheritance and polymorphism built right in
13. What is a Class?
A class in Python acts like a blueprint fro making objects This sets up the object’s properties and behaviors with variables and functions Classes organize programs by using components that can be reused
14. What is an Object?
An object refers to a case of a class that has both data and methods. It is very similar to a live nature that has different feelings and behaviors. The class can produce different objects, but each of them will have its own distinct values.
15. What is Inheritance?
One class can get the stuff and actions from another class through inheritance It cuts down on unnecessary code and makes it easier to reuse in apps Python lets you do different kinds of inheritance, like going up and down levels, or having more than one at the same time
16. What is Polymorphism?
Polymorphism lets the same function or method act differently based on the object that’s using it This boosts flexibility and keeps the code neat and tidy Python lets you do different things with the same method or use built-in functions that work in various ways
17. What is Encapsulation?
Hiding private or protected data, encapsulation keeps it safe It keeps the inner workings of an object private This boosts data safety and stops unintended changes
18. What is Abstraction?
Abstraction keeps the gritty details under wraps and shows just what you need to know Simplifying programming makes it easier for users by cutting out the extra stuff they don’t need Abstract classes and interfaces make it easier to work with abstraction in Python
19. What is the init() method?
The __init__() method is automatically called when we create an object It sets up object properties with standard or custom values This method sets up the data needed for object operations
20. What is Method Overloading?
Python doesn’t have teh same method overloading feature that java does But you can get the same thing done with default parameters This lets a single function deal with varying amounts of arguments
21. What is Method Overriding?
When a child class redefines a method with the same name as one in its parent class, that’s method overriding The child class can offer its own way of doing things This allows for runtime polymorphism and adaptable behavior
22. What are Python libraries?
Python libraries are like toolboxes filled with ready-to-use code snippets They speed up app development by not starting from zero Libraries like NumPy, Pandas, and Matplotlib are quite popular
23. What is a Virtual Environment?
A virtual environment keeps project dependencies in their own space It stops arguments between various project updates and components Python lets you set up these isolated spaces .
24. What are Python Exceptions?
Runtime glitches are those annoying bugs that cause problems when your program is running. Python employs try-except blocks to deal with these errors so as not to crash. Handling errors in a proper way makes programs more reliable and friendly to end users.
25. What is a Try-Except Block?
Error handling in runtime: Try- except block. The code inside a try block is executed, while catching the error proceeds in the except block. The software keeps running smoothly even when issues arise
26. What is Type Casting?
Converting one data type to another, like turning an int into a float, is what we call type casting This makes it easier to match up during a calculation or comparison Python lets you change types on the fly when you’re doing stuff
27. What is a Loop in Python?
A loop allows the execution of a block of code repeatedly Python primarily has for-loops and while-loops for iteration tasks. Loops have made the automation of tedious processes easy and efficient.
28. What is a List Comprehension?
List comprehension is a cool technique for creating new lists quickly. It makes the code more readable by merging loops and conditions into one line. The performance of the code is not only increased but also the new method is quite readable when compared against the traditional looping paradigm.
29. What is a Generator in Python?
In Python, generators are special kinds of functions that return one value at a time with the yield keyword instead of returning all at once which is a memory-efficient way in case of huge data.
30. What is the Difference Between List and Tuple?
The list is adjustable; it is flexible and allows changing and deleting. A tuple is like a collection of elements that once it is created, cannot be altered. Lists are very useful for data that is constantly changing, whereas tuples are the preferred type for data that needs to be preserved and immutable.
31. What is the Global Keyword?
The global keyword in Python lets you change a variable that’s been set outside of a function Variables inside functions are local unless specified otherwise This lets functions share and tweak shared data
32. What does Scope in Python mean?
The word “scope” is used to refer to the space where a certain variable can exclude any other details pertaining to the level at which the variable is used. It has four scopes in Python – local, global, nonlocal, and builtin. Good scoping practices support that variables are always used within their bounds.
33. What is the Decorator in Python?
The decorator is like a helper that boosts another function by throwing in some extra features It lets you tweak how things work without messing with the actual code Decorators are commonly employed in logging, authentication, and validation
34. What is a File Handling in Python?.
File management lets you read, write, and tweak files using Python. It makes use of functions like open(), read(), and write() for different operations. Data storage keeps files outside the program
35. What are the data types in Python?
In Python, the fundamental data types are six: int, float, string, list, tuple, and dictionary. Data can be classified according to their usage and type. Data can be differentiated by their use and type. The right one is a key factor for the program’s smooth running.
36. What is Slicing in Python?
Cutting out parts of lists, strings, or tuples using index ranges this offers easy and efficient ways to get at specific parts of the data Slicing uses the [start:end:step] format for extraction
37. What is a Docstring?
A docstring is a documentation that is written inside triple quotes at the beginning of a function or class. This explains what each part of the code does and how it’s used Docstrings make it easier for developers to get what’s going on in the code when they’re fixing it up
38. What is a Python Interpreter?
The interpreter executes a Python program one statement at a time It also may be thought of as dynamically converting source code into machine-readable instructions.
39. What is Pickling in Python?
Converting stuff into bytes for saving it It lets you store complicated data structures for future use Python uses the pickle module for turning objects into a storable format and then back into objects
40. What is a Namespace?
A namespace is similar to a container where you store all your variable names with their respective values. It is an effective measure against name collisions in large programming projects. Python has its own namespaces like global, local, and built-in as well.
40. What is a Namespace?
A namespace is like a storage box where you keep all your variable names and their values together Using namespaces is a smart way to avoid naming clashes in big code projects Python’s got its own set of namespaces, including global, local, and built-in ones
41. What is a Map Function?
The map function applies a specific function to every item in a list or sequence It gives back a map with all the processed stuff This streamlines changes and skips the need fro hand-coding loops
42. What is a Filter Function?
The filter function picks out items from a list when they meet a certain criteria It brings back stuff that works with the function you’re looking for It’s often used for sorting and checking data
43. What is Reduce Function?
The reduce function takes a function and applies it step by step to elements in a list, building up a single result It’s used to calculate stuff like adding things up or multiplying numbers You can use the reduce function from the function tools module in Python
44. What is a Python Script?
A Python script is in essence a file containing executable Python code with the extension .py. It may be created for task automation or direct programming execution. Typically, scripts are executed using the Python interpreter.
45. What is Indentation in Python?
Indentation in Python tells us where our code blocks start and end, taking the place of curly braces It makes sure the interpreter gets the hang of the code’s layout and organization Keeping things neat with proper spacing helps prevent code mistakes
46. What’s the difference between == and is
The function verifies if two objects are identical by comparing their memory addresses Results might vary based on how data’s stashed
47. What is Mutable and Immutable?
Things like lists and dictionaries can be changed up after they’re made Objects like tuples and strings are unchangeable Grasping both aids in handling memory and steering program actions
48. What is Recursion?
Recursion is a coding trick where a function keeps calling itself over and over again Breaks down complex issues into more manageable parts To avoid endless cycles, you’ve got to set the right starting conditions
49. What is Multithreading?
Multithreading is a technique that allows concurrent execution of multiple threads within a single program This can be a great feature in performance boost in cases where the operations involve waiting or I/O operations. Python supports threads and their management through the threading module.
50. What is Python Used For?
Python’s a go-to for web dev, data science, machine learning, automation, and scripting Libraries and straightforward syntax make it versatile for different fields It’s super popular around the world these days
