Python interview questions:
What is Python?
Python is a high-level, interpreted programming language that is widely used for web development, data analysis, and scientific computing.
What are the advantages of using Python?
Python is easy to learn, read, and write, and has a large and active community that contributes to its development. It has a vast library of modules and packages that make development faster and more efficient, and can be used for a wide range of applications, including web development, data analysis, scientific computing, and machine learning.
What is PEP 8?
PEP 8 is a set of guidelines for writing Python code that promotes consistency and readability. It covers topics such as indentation, naming conventions, and coding style.
What is a Python module?
A Python module is a file containing Python code that can be imported into other Python programs. Modules are used to organize and reuse code, and to make programming more efficient.
What is a Python package?
A Python package is a collection of Python modules that are organized in a directory hierarchy. Packages are used to organize and reuse code across multiple projects.
What is the difference between a list and a tuple?
A list is a mutable sequence of elements that can be modified, added, or removed. A tuple is an immutable sequence of elements that cannot be modified once it is created.
What is a dictionary in Python?
A dictionary is a collection of key-value pairs that can be used to store and retrieve data. Keys in a dictionary must be unique and immutable, while values can be any data type.
What is a lambda function?
A lambda function is an anonymous function that can be defined on a single line of code. It is often used to define simple functions that are only used once.
What is a decorator in Python?
A decorator is a special function that can modify or enhance the behavior of another function. It is often used to add functionality to existing functions without modifying their code.
What is a generator in Python?
A generator is a special type of function that generates a sequence of values on-the-fly. It is often used to create memory-efficient code that processes large datasets.
