Python Fresher Interview Q & A

Python is a high-level, interpreted programming language known for its simplicity and readability. It's widely used in various fields such as web development, data science, machine learning, artificial intelligence, automation, and more. Python supports multiple programming paradigms including procedural, object-oriented, and functional programming.

To clear a Python interview as a fresher, it's important to have a good understanding of the language fundamentals, data structures, and basic algorithms. Here are some important Python questions that are often asked in interviews for freshers:

1. What is Python? What are its key features?
2. Differentiate between Python 2 and Python 3.
3. Explain Python's dynamic typing.
4. Discuss the differences between lists and tuples in Python.
5. What are the built-in data types in Python?
6. Explain the concept of mutable and immutable types in Python.
7. What is PEP 8? Why is it important?
8. How does memory management work in Python?
9. Explain the difference between `==` and `is` operators in Python.
10. Discuss the concept of namespaces in Python.
11. What is a generator in Python?
12. Explain the purpose of `__init__` method in Python classes.
13. What is the difference between `staticmethod` and `classmethod`?
14. Discuss the significance of Python's `with` statement.
15. Explain the concept of inheritance in Python.
16. How does exception handling work in Python?
17. What are decorators in Python? Provide an example.
18. Explain the use of lambda functions in Python.
19. How do you install external packages in Python?
20. Discuss the difference between `__str__` and `__repr__` methods in Python.

In addition to these technical questions, it's also important to practice coding exercises, understand basic algorithms and data structures, and be able to solve problems using Python. Online coding platforms such as LeetCode, HackerRank, and CodeSignal are great resources for practicing coding problems in preparation for interviews. Additionally, reviewing sample projects and being able to discuss your understanding of them can also be helpful.
