3. What are Python’s built-in data types?
Common built-in types include:
int, float, complex, str, list, tuple, set, dict, bool, and NoneType.
4. What is the difference between == and is?
== compares values, while is checks whether two references point to the same object.
a = [1, 2]
b = [1, 2]
print(a == b) # True
print(a is b) # False
5. What is the difference between mutable and immutable objects?
Mutable objects can be changed after creation. Lists, dictionaries, and sets are examples.
Immutable objects cannot be changed after creation. Strings, integers, floats, and tuples are common examples.
6. What are Python variables?
A variable is a name that refers to an object.
name = “Rahul”
age = 22
Python does not require you to explicitly declare the variable’s data type.
7. What is indentation in Python?
Indentation defines blocks of code in Python.
if age >= 18:
print(“Eligible”)
Incorrect indentation can cause an IndentationError.
Python OOP Interview Questions
Object-oriented programming is an important topic for Python interviews because many real-world applications are built using classes and objects.
8. What is OOP in Python?
Object-oriented programming organizes software around objects that contain data and behavior.
The major OOP concepts are:
- Encapsulation
- Inheritance
- Polymorphism
- Abstraction
9. What is a class?
A class is a blueprint for creating objects.
class Student:
def __init__(self, name):
self.name = name
10. What is an object?
An object is an instance of a class.
student = Student(“Rahul”)
Here, student is an object of the Student class.
11. What is inheritance?
Inheritance allows one class to reuse attributes and methods from another class.
class Animal:
def speak(self):
print(“Animal speaks”)
class Dog(Animal):
pass
Dog inherits from Animal.
12. What is polymorphism?
Polymorphism allows the same interface or method name to behave differently depending on the object using it.
13. What is encapsulation?
Encapsulation involves grouping data and methods together and controlling how internal data is accessed or modified.
14. What is self in Python?
self refers to the current instance of a class.
class Student:
def show(self):
print(self)
15. What is __init__()?
__init__() is commonly used to initialize an object’s attributes when an instance is created.
class Student:
def __init__(self, name):
self.name = name
Python Coding Interview Questions
Coding questions test whether you can apply Python concepts to solve problems.
16. How do you reverse a string in Python?
text = “Python”
print(text[::-1])
Output:
nohtyP
17. How do you check whether a number is even or odd?
number = 10
if number % 2 == 0:
print(“Even”)
else:
print(“Odd”)
18. How do you check whether a string is a palindrome?
text = “madam”
if text == text[::-1]:
print(“Palindrome”)
else:
print(“Not a palindrome”)
19. How do you find the largest number in a list?
numbers = [10, 25, 7, 40, 15]
print(max(numbers))
In an interview, you may also be asked to solve this without using max(). Practice both approaches.
20. How do you count the frequency of characters in a string?
A dictionary can be used to store each character and its count.
text = “python”
frequency = {}
for char in text:
frequency[char] = frequency.get(char, 0) + 1
print(frequency)
21. How do you remove duplicates from a list?
For a simple case:
numbers = [1, 2, 2, 3, 3, 4]
unique = list(set(numbers))
If the original order must be preserved, use a different approach rather than relying on a set alone.
Python Interview Questions for Beginners
Beginners should be comfortable with basic programming concepts before moving into advanced Python topics.
22. What is a loop in Python?
A loop executes a block of code repeatedly.
Python commonly uses:
- for
- while
Example:
for number in range(5):
print(number)
23. What is the difference between break, continue, and pass?
break exits the loop.
continue skips the current iteration.
pass performs no action and is commonly used as a placeholder.
24. What is a function?
A function is a reusable block of code.
def greet(name):
return “Hello ” + name
25. What is a lambda function?
A lambda is a small anonymous function.
square = lambda x: x * x
print(square(5))
26. What is exception handling?
Exception handling allows programs to respond to runtime errors.
try:
result = 10 / 0
except ZeroDivisionError:
print(“Cannot divide by zero”)
27. What is a module?
A module is a Python file containing reusable code such as functions, classes, and variables.
import math
print(math.sqrt(25))
Scenario-Based Python Interview Questions
This section is important because interviews often move beyond definitions and ask how you would handle a practical problem.
28. What would you do if your Python program is running slowly?
First, identify where the performance problem occurs rather than changing code randomly.
You could:
- Profile the application.
- Identify slow functions or operations.
- Check inefficient loops and data structures.
- Reduce unnecessary calculations.
- Optimize database or API calls.
- Consider caching where appropriate.
29. How would you handle invalid user input?
Validate the input and use exception handling where appropriate.
try:
age = int(input(“Enter your age: “))
except ValueError:
print(“Please enter a valid number.”)
30. What would you do if an API suddenly starts returning errors?
Check the HTTP status code, response body, request parameters, authentication, rate limits, and API documentation.
Do not immediately assume the Python code is the problem.
31. How would you debug a Python program?
A good approach is:
Reproduce → isolate → inspect → fix → test.
Use clear logging, debugging tools, test cases, and error messages instead of changing multiple things at once.
Python Interview Questions on Lists, Tuples and Dictionaries
32. What is the difference between a list and tuple?
A list is mutable:
numbers = [1, 2, 3]
A tuple is immutable:
numbers = (1, 2, 3)
33. What is a dictionary?
A dictionary stores data using key-value pairs.
student = {
“name”: “Rahul”,
“age”: 22
}
34. Why are dictionaries useful?
Dictionaries provide a convenient way to associate keys with values and are widely used for structured data, configuration, lookup operations, and counting.
35. What is list comprehension?
List comprehension provides a concise way to create a list.
squares = [x * x for x in range(5)]
36. When should you use a tuple instead of a list?
Use a tuple when the collection represents data that should not be modified after creation.
For example:
coordinates = (17.385, 78.486)
