Python Developer (Fresher) – Interview Questions and Answers

1. Can you explain what Python is and why it is popular?

Answer:
Python is a high-level programming language that is easy to read and write. It is popular because of its simple syntax, which looks like English, and its large set of libraries. Python can be used for many purposes like web development, data science, automation, and artificial intelligence. Companies prefer Python because it reduces development time and makes code easier to maintain.

2. What are Python’s key features?

Answer:
Python has many useful features such as:

It is interpreted, meaning code runs line by line.
It is object-oriented, which helps in reusability and better structure.
It has a huge number of libraries and frameworks like Django, Flask, NumPy, and Pandas.
It is cross-platform, so the same code can run on Windows, Linux, or Mac.
It supports dynamic typing, meaning you don’t need to declare variable types explicitly.

3. What are Python data types? Can you explain with examples?

Answer:
Python has several built-in data types, such as:

int – for whole numbers (e.g., x = 10)
float – for decimal numbers (e.g., pi = 3.14)
str – for text or strings (e.g., name = "Krishna")
list – ordered collection (e.g., fruits = ["apple", "banana", "mango"])
tuple – immutable collection (e.g., colors = ("red", "blue"))
dict – key-value pairs (e.g., student = {"name": "Rahul", "age": 20})
set – unique unordered collection (e.g., nums = {1, 2, 3, 3})

4. Can you explain the difference between List, Tuple, and Set?

Answer:

List: A collection that is ordered and changeable. Example: list1 = [1, 2, 3]. You can add, remove, or modify elements.
Tuple: A collection that is ordered but cannot be changed. Example: tuple1 = (1, 2, 3). Once created, you cannot modify elements.
Set: A collection that is unordered and does not allow duplicate values. Example: set1 = {1, 2, 3, 3} → it will store only {1, 2, 3}.

5. What is Object-Oriented Programming (OOP) in Python?

Answer:
OOP is a way of writing programs where we group data and functions together in the form of classes and objects.

A class is like a blueprint (for example, a “Car” class).
An object is a real example created from a class (for example, myCar = Car()).
OOP makes code easier to reuse and maintain.

6. What is the difference between Python’s == and is operators?

Answer:

== checks if two values are equal. Example: 5 == 5 → True.
is checks if two objects are the same in memory. Example:

a = [1, 2] b = [1, 2] print(a == b) # True, values are equal print(a is b) # False, because they are stored in different memory locations

7. What is PEP 8 and why is it important?

Answer:
PEP 8 is the official style guide for writing Python code. It provides rules on naming variables, indentation, line spacing, and commenting. Following PEP 8 makes code cleaner, easier to read, and more professional.

8. What are Python modules and packages?

Answer:

Module: A single Python file with reusable functions or classes. Example: math.py.
Package: A collection of modules stored in a folder with an __init__.py file. Example: numpy is a package with many modules inside it.

9. What is the difference between Flask and Django?

Answer:

Flask: A lightweight web framework. It gives developers flexibility and is good for small projects.
Django: A full-featured framework with built-in tools like authentication, admin panel, and ORM. It is better for large applications.

10. Can you explain how Python connects with databases?

Answer:
Python can connect to databases like MySQL, PostgreSQL, or MongoDB using libraries. For example:

SQLite: Built-in library in Python.
MySQL Connector: mysql-connector-python package.
SQLAlchemy: Popular ORM library for handling database operations easily.
Using these, you can insert, update, and fetch data from databases.

11. What is Git and why is it used in development?

Answer:
Git is a version control system that helps track changes in code. It allows developers to work together, store project history, and roll back if something goes wrong. Platforms like GitHub or GitLab use Git for code collaboration.

12. Can you explain exception handling in Python?

Answer:
Exception handling is used to manage errors without stopping the program. Example:

try:

num = int("abc")

except ValueError:

print("Invalid input")

finally:

print("Program ended")

Here, try checks the code, except handles the error, and finally always executes.

13. What are some commonly used Python libraries?

Answer:

NumPy: For numerical calculations.
Pandas: For data analysis.
Matplotlib: For data visualization.
Requests: For making HTTP requests.
Flask/Django: For web development.

14. Why do you want to join CGI as a Python Developer?

Answer:
CGI is one of the largest IT consulting firms in the world. Joining as a Python Developer gives me the chance to work on real projects, learn from experienced professionals, and grow my career. I am excited to be part of a team that values teamwork, ownership, and innovation.

15. How do you keep yourself updated with Python technologies?

Answer:
I regularly practice coding on platforms like HackerRank and LeetCode. I also follow Python documentation, watch tutorials, and read blogs about new frameworks and tools. This helps me stay updated and improve my skills.
