Must-Know Python Interview Questions for Every Developer! 🚀 #Python #InterviewQuestions #Coding

Here are the top 5 Python interview questions with answers:

1️⃣ What are *args and **kwargs in Python?

*args allows passing a variable number of positional arguments to a function.
**kwargs allows passing a variable number of keyword arguments as a dictionary.

def example_function(*args, **kwargs):
print("Positional arguments:", args)
print("Keyword arguments:", kwargs)

example_function(1, 2, 3, name="Alice", age=25)
Output:

Positional arguments: (1, 2, 3)
Keyword arguments: {'name': 'Alice', 'age': 25}

2️⃣ How does list comprehension work in Python?

A compact way to create lists using a single line of code.
Faster and more readable than traditional loops.

# Traditional loop
numbers = []
for i in range(5):

# List comprehension
numbers = [i * 2 for i in range(5)]
print(numbers) # [0, 2, 4, 6, 8]

3️⃣ What is the difference between @staticmethod, @classmethod, and an instance method?

Instance Method: Works with self and can modify object attributes.

class Example:
def instance_method(self):
return "Instance Method"

@classmethod
def class_method(cls):
return "Class Method"

@staticmethod
def static_method():
return "Static Method"

obj = Example()

4️⃣ What is the difference between Python’s del statement and remove() method?

del deletes a variable or an item by index and raises an error if the variable is accessed afterward.
remove() removes an element by value from a list.

my_list = [1, 2, 3, 4, 5]
del my_list[2] # Removes element at index 2
print(my_list) # [1, 2, 4, 5]

print(my_list) # [1, 2, 5]

5️⃣ What is monkey patching in Python?

Dynamically modifying a module or class at runtime.
Often used for testing or quick fixes but can lead to maintenance issues.

class Example:
def say_hello(self):
return "Hello, World!"

def new_hello(self):
return "Hello, Python!"

obj = Example()
