Python interview questions and answer — 2023 | Python developer roadmap

If you’re interviewing for a data science, backend developer, or any role that involves programming with Python, be prepared to answer these basic questions.

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

Lists can be changed (mutable), while tuples cannot be changed (immutable). Tuples are also often used to store data that won’t be modified, such as coordinates in a game or names in a list.

2. What is the difference between == and is

The difference between == and `is` is that == compares the values of two objects, while `is` compares the identity of two objects. The identity of an object is its memory address.

3. What is the difference between a global and a local variable in Python?

A global variable can be accessed from anywhere in the code, while a local variable can only be accessed within the scope it was declared.

4. What is the difference between xrange and range in Python?

xrange is an iterator while range returns a list. xrange is also faster and uses less memory than range.
