Python Interview Question
Here are some common Python interview questions, along with some possible answers:
- What is Python?
Python is a high-level, interpreted programming language that is widely used for web development, scientific computing, data analysis, artificial intelligence, and more. It is known for its simple syntax, readability, and support for multiple programming paradigms.
- What are the main features of Python?
Some of the main features of Python include:
- A simple, easy-to-learn syntax
- Dynamic Semantics
- High-level built-in data structures (such as lists and dictionaries)
- Support for multiple programming paradigms (such as object-oriented, functional, and procedural programming)
- A large and active community
- A wide range of libraries and frameworks for various tasks
- What is the difference between a list and a tuple in Python?
A list is a mutable data structure, which means that its elements can be modified after it is created. A tuple is an immutable data structure, which means that its elements cannot be modified after it is created.
- What is a python decorator?
A Python decorator is a function that modifies the behavior of another function. Decorators are typically used to add functionality to existing functions, such as logging, caching, or authentication. They are also used to define class methods and static methods.
- What is a Python generator?
A Python generator is a special type of function that can be used to create an iterator. It uses the “yield” keyword instead of “return” to return a value, and it can be called multiple times to generate a sequence of values. Generators are useful for working with large data sets or for creating infinite sequences of values.
- What is the difference between deep and shallow copy?
A deep copy creates a new object with a new memory address and copies all the values of the original object into it. A shallow copy, on the other hand, creates a new object with a new memory address that points to the same values as the original object.
- What is PEP 8?
PEP 8 is a set of coding conventions for Python. It is a style guide that provides a set of guidelines for writing Python code, such as using four spaces for indentation, limiting lines to 79 characters, and using lowercase letters and underscores for variable and function names.
- What is a namespace in Python? A namespace is a container that holds a set of identifiers. In Python, namespaces are implemented as dictionaries, and they are used to keep track of variables, functions, and class names. Each module has its own namespace, and the global namespace contains names defined in the main module.
These are just a few examples of common interview questions for Python developers. It is important to note that the specific questions will vary depending on the company and the specific role you are applying for. However, by understanding the concepts outlined in these questions, you will be well-prepared for your interview.
