Python interview questions for beginners:

Certainly! Below are some common Python interview questions for beginners along with brief answers. These questions cover fundamental concepts and are often used to assess a candidate’s understanding of basic Python programming.

1. What is Python?

Answer:  Python is a high-level, interpreted, and general-purpose programming language known for its simplicity and readability. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming.

2. How do you comment in Python?

Answer: Comments in Python start with the # symbol. Everything following the # on that line is treated as a comment and is ignored by the interpreter.

3. What is the difference between list and tuple in Python?

Answer: Lists are mutable (can be modified), while tuples are immutable (cannot be modified). Lists are defined using square brackets [], and tuples use parentheses ().

4. Explain the concept of a dictionary in Python.

Answer: A dictionary is an unordered collection of key-value pairs. Each key must be unique, and it is associated with a value. Dictionaries are defined using curly braces {}.

5. How do you handle exceptions in Python?

Answer: Exceptions are handled using try, except blocks. Code that might raise an exception is placed in the try block, and the handling code is placed in the except block.

6. What is the purpose of _init_ in Python classes?

Answer: __init__ is a special method in Python classes that is called when an object is created. It is used to initialize the attributes of the object.

7. Explain the difference between ‘==’ and ‘is’ in Python.

Answer: == checks for equality of values, whereas is checks for object identity. == compares the values of the objects, and is checks if two objects refer to the same memory location.

8. What is the purpose of the ‘if _name_ == “_main_”:’ statement?

Answer: It checks whether the Python script is being run as the main program or if it is being imported as a module. Code inside this block will only run if the script is the main program.

9. How can you reverse a list in Python?

Answer: You can reverse a list using the reverse() method or by using slicing with [::-1].

10. What is the use of ‘pass’ statement in Python?

Answer: The `pass` statement is a no-operation statement. It serves as a placeholder where syntactically some code is required but no action is desired or necessary.

11. How do you read user input in Python?

Answer: User input can be read using the `input()` function. For example:

“`python

user_input = input(“Enter something: “)

“`

12. What is a virtual environment in Python?

Answer: A virtual environment is a self-contained directory that contains a Python interpreter and libraries. It allows you to create isolated environments for different projects, preventing conflicts between dependencies.
