Python Interview Questions and Answers for Freshers
Python is widely used for web development, automation, data analysis and artificial intelligence. Students preparing for technical interviews should understand both programming concepts and practical examples.
1. What is Python?
Python is a high-level, general-purpose programming language known for its readable syntax and extensive standard library.
Example:
print("Hello, Python!")
2. What is the difference between a list and a tuple?
Lists are mutable, while tuples are immutable.
Example:
numbers = [10, 20, 30]
numbers[0] = 50
coordinates = (10, 20)
print(numbers)
3. What is a dictionary?
A dictionary stores key-value pairs.
Example:
student = {"name": "Amit", "course": "BCA"}
print(student["name"])
4. What is a function?
A function is a reusable block of code.
Example:
def add(a, b):
return a + b
print(add(10, 20))
5. What is exception handling?
Exception handling helps programs respond to runtime errors.
Example:
try:
number = int(input("Enter number: "))
print(100 / number)
except ValueError:
print("Invalid integer")
except ZeroDivisionError:
print("Cannot divide by zero")
6. What is a class?
A class defines attributes and methods for objects.
Example:
class Student:
def __init__(self, name):
self.name = name
def show(self):
return self.name
student = Student("Riya")
print(student.show())
7. What is inheritance?
Inheritance allows one class to reuse or extend another class's behavior.
8. What is list comprehension?
List comprehension creates lists using concise expressions.
Example:
squares = [x * x for x in range(1, 6)]
print(squares)
9. What is a module?
A module is a Python file containing reusable code.
Example:
import math
print(math.sqrt(64))
10. What is a generator?
A generator produces values on demand, often using yield.
Example:
def numbers():
yield 1
yield 2
yield 3
for number in numbers():
print(number)
Practical Coding Exercises
Reverse a string
text = "Python"
print(text[::-1])
Check an even number
number = 24
print(number % 2 == 0)
Find the largest number
numbers = [12, 45, 8, 67]
print(max(numbers))
Count vowels
text = "Programming"
count = sum(1 for c in text.lower() if c in "aeiou")
print(count)
Interview Preparation Tips
Practice variables, loops, functions, lists, dictionaries, exception handling and object-oriented programming.
Build small applications such as an expense tracker, student marks calculator or contact manager.
Frequently Asked Questions
Is Python suitable for beginners?
Yes. Python has readable syntax and is approachable for students learning programming.
Do freshers need object-oriented programming?
Many entry-level interviews cover classes, objects, constructors and inheritance.
Is Python alone enough for a software career?
Python is a useful foundation, but databases, debugging, Git and practical projects are also important.
Conclusion
Python interview preparation becomes more effective when students combine theoretical knowledge with practical coding exercises. Practice consistently and learn to explain your solutions.
