This comprehensive list of Python interview questions will help you ease your Python programming job interview.

1. What is your understanding of Python?

Python is a scripting language that is extremely comprehensive, interactive, and object-oriented. It was created with the intention of making the text more readable for internet users. Apart from punctuation, it uses a variety of keywords in other languages. Unlike other languages, it contains fewer syntactic structures. Python is used to create AI-based intuitive web and mobile app development.

2. What are the benefits of using Python?

Python is a programming language that features objects, modules, threads, exceptions, and memory management that is automatic. Its advantages are well-known. It is simple and straightforward to use, portable, extensible and has a built-in structure while being open-source. 

3. What is pickling and unpickling?

Pickle takes any Python object and converts it to a string representation, which it then dumps into a file using the dump function. Pickling is the name for this method. Whereas, the process of recovering original Python objects from a stored text representation is known as unpickling.

4. How is Python interpreted?

Python is an interpreted programming language. Python programs are compiled from source code and run directly. It translates the programmer’s source code into an intermediate language, which is then translated into machine language, which must be executed.

5. How is memory managed in Python?

Memory management is handled via Python’s own heap space. All Python objects and data structures are stored in a private heap. This private heap, which is controlled by the Python interpreter, is not accessible to the programmer.

Allocating heap space for Python objects is handled by Python memory management. Programmers can use the core API to access some programming tools.

Python has a built-in garbage collector that recycles all unused memory, freeing it and making it available to the heap.

6. What are Python namespaces?

In Python, a namespace refers to the name that is assigned to each object. Variables and functions are the objects. Each object’s name and space (the address of the outer function in which the item is) are created as it is formed. The namespaces are stored in Python as a dictionary, with the namespace as the key and the object’s address as the value. In Python, there are four different types of namespaces:

  1. Built-in namespace– These namespaces contain all of Python’s built-in objects and are accessible at all times.
  2. Global namespace– These are the namespaces for all of the objects created at the main program level.
  3. Enclosing namespaces– These namespaces belong to the higher or outer function.
  4. Local namespaces– These namespaces are found in the inner or local function.

7. What are decorators in Python?

Decorators are used to change the appearance of a function without changing its structure. Decorators are usually defined prior to the function they will be enhancing. To use a decorator, we must first specify its function. Then we write the function to which it will be applied and simply place the decorator function above the function to which it will be applied. The @ symbol is used before the decorator in this case.

8. What is the difference between a list and a tuple?

The difference between a list and a tuple is that a list can be mutated, whereas a tuple cannot. A Tuple can be hashed as a dictionary key, for example.

9. How are arguments passed by value or by reference?

In Python, everything is an object, and all variables are references to objects. The functions determine the reference values. As a result, you won’t be able to change the value of the references. If the objects are mutable, you can change them.

10. What built-in type does python provide?

Python provides two built-in types: 

1) Mutable and 2) Immutable.

Mutable built-in types are:

  • List
  • Sets
  • Dictionaries
  • Immutable built-in types
  • Strings
  • Tuples
  • Numbers

Immutable built-in types are:

  • Strings
  • Tuples
  • Numbers

11. What is slicing in Python?

Slicing is a technique for gaining access to specific bits of sequences such as lists, tuples, and strings. [start:end:step] is the slicing syntax. This step can also be skipped. When we type [start:end], we get a list of all the elements in the sequence from the beginning (inclusive) to the end-1 element. It means the ith element from the end if the start or end element is negative i. The step represents the jump or the number of components that must be skipped. If there is a list, for example, [1,2,3,4,5,6,7,8]. Then, by printing every second element, [-1:2:2] will return elements from the last to the third element. [8,6,4] is an example.

12. What are python modules? Name some commonly used built-in modules in Python?

Python modules are executable files that contain Python code. Functions, classes, and variables can all be used in this code. A Python module is a .py file that contains code that may be executed.

The following are some of the most often used built-in modules:

  • os
  • sys
  • math
  • random
  • data time
  • JSON

13. Is indentation required in python?

Indentation is required in Python. It designates a coding block. An indented block contains all of the code for loops, classes, functions, and so on. The most common method is to use four space characters. Your code will not execute correctly if it is not indented, and it will also throw errors.

14. What is self in Python?

A class’s instance or object is called Self. This is explicitly supplied as the first parameter in Python. However, in Java, where it is optional, this is not the case. With local variables, it’s easier to distinguish between a class’s methods and attributes.

In the init method, the self variable refers to the newly created object, whereas it relates to the object whose method was called in other methods.

15. What are negative indexes and why are they used?

In Python, the sequences are indexed and include both positive and negative numbers. The positive numbers utilize ‘0’ as the first index and ‘1’ as the second index, and the procedure continues in this manner.

The index for a negative number begins with ‘-1,’ which is the last index in the sequence, and ends with ‘-2,’ which is the penultimate index, and the sequence continues as it does for a positive number.

The negative index is used to remove any new-line spaces from the string, allowing it to accept the S[:-1] character as the final character. The negative index is also used to represent the index in the correct order of the string.
