Python Interview Questions for Fresher

1. What is PIP in Python?

PIP is the standard package manager for Python. It allows us to install and manage additional packages that are not part of Python.

2. What type of language is Python? Programming or Scripting?

Python is technically a scripting language, but in a general sense, it is considered as a general-purpose programming language.

Basically, all scripting languages are programming languages. The theoretical difference between the two is that scripting languages do not require the compilation step and are rather interpreted.

3. What are the key features of Python?

Key features of Python language are:

Free and Open Source:

Python language is freely available at the official web address ( The source code is also available, therefore it is open source.

Object-Oriented Language:

Python supports object-oriented language and concepts of classes and objects that come into existence.

Easy to Learn and Use:

Python is easy to learn and use. It is a developer-friendly and high-level programming language.

Cross-platform Language:

Python can run equally on different platforms such as Windows, Linux, Unix, and Macintosh, etc. So, we can say that Python is a portable language.


It can be easily integrated with languages like C, C++, JAVA, etc.

Note: Python has so many other features also there, but here I mentioned key features only.

4. What are the different implementations of Python?

Python has a number of alternative implementations are available:

CPython: The default implementation of the Python programming language is CPython. As the name suggests CPython is written in C language.

IronPython: (Python running on . NET)

Jython: (Python running on the Java Virtual Machine)

PyPy: (A fast Python implementation with a JIT compiler)

Stackless Python: (Branch of CPython supporting micro-threads)

MicroPython: (Python running on microcontrollers)

Anaconda Python: Anaconda is a free and open-source distribution of the Python and R programming languages for scientific computing.

5. How is Python an interpreted language?

Python is called an interpreted language because it goes through an interpreter, which turns code you write into the language understood by your computer’s processor.

An interpreted language is any programming language that isn’t already in “machine code” prior to runtime. Unlike compiled languages , an interpreted language’s translation doesn’t happen beforehand. Translation occurs at the same time as the program is being executed.

6. What is PEP 8 in Python?

PEP 8 is Python’s style guide. It’s a set of rules for how to format your Python code to maximize its readability.

PEP-8 (Python Enhancement Proposal) presents some of the key points that you can use to make your code more organized and readable.

7. What is PYTHON PATH?

PYTHONPATH is an environment variable that is used when a module is imported. For most installations, you should not set these variables since they are not needed for Python to run. Python knows where to find its standard library. You can also select the Path option while Python installation.

8. How to write & execute Python Programs?

You need to have Python Environment to write & execute/run Python programs,

Example: In Windows operating system, download & Install Python software, then you can get Python IDLE, using Python IDLE you can write & execute Python programs, otherwise download & install PyCharm like IDE, and using PyCharm IDE you can write & execute Python programs.

Note: Python IDLE is best for learning and PyCharm IDE is best for real-time use.

9. How Python is Object Oriented Programming Language?

Python is an object-oriented programming language and it also supports procedural programming.

Python allows us to develop applications using an Object-Oriented approach. In Python, we can easily create and use classes and objects.

Python supports all major principles of object-oriented programming system concepts like Object, Class, Method, Inheritance, Polymorphism, Data Abstraction, and Encapsulation.

10. What is a Local variable in Python?

A local variable is limited to the function where it is defined.

11. How to define Data types in Python?

No explicit declaration of Data types in Python, you can store any type of value to a variable, Python considers the data type based on the usage of data, and we can get the data type of any object by using the type() function.

12. What are docstrings in Python?

Python documentation strings (or docstrings) provide a convenient way of associating documentation with Python modules, functions, classes, and methods.

13. What are the Python Collections?

Collections in python are basically container data types, namely lists, sets, tuples, and dictionaries. They have different characteristics based on the declaration and the usage.

14. How to read User Input in Python?

Python user input from the keyboard can be read using the input() built-in function.

15. How to write code blocks in Python?

Python programs get structured through indentation, i.e. code blocks are defined by their indentation.

16. How to insert Comments in Python Programs?

A hash sign (#) begins a comment, all characters after the # and up to the end of the physical line are part of the comment.


#This is a comment

Python does not really have a syntax for multi-line comments, You can add a multi-line string (triple quotes) in your code, and place your comment inside it.


This is a comment
written in
more than just one line

17. What are the Python Numbers?

Python supports integers, floating-point numbers, and complex numbers. They are defined as int, float, and complex classes in Python.


print(type(a)) #int



18. How to print Output in Python?

Using print() function (built-in function) we can print the output in Python,


print (“Hello Python”) #Output is Hello Python

print (x) #Output is 100

name=”G C Reddy”
print(“My Name is: ” + name) #Output is G C Reddy

19. What is lambda in Python?

In Python, an anonymous function is a function that is defined without a name.

While normal functions are defined using the def keyword in Python, anonymous functions are defined using the lambda keyword.

Hence, anonymous functions are also called lambda functions.

20. What is self in Python?

The self parameter is a reference to the current instance of the class and is used to access variables that belong to the class.
