Membership operators in Python are used to test whether a value or variable exists in a sequence (such as a string, list, tuple, set, or dictionary). There are two membership operators: in and not in.

in Operator: This operator checks if a specified value is present in a sequence. If the value is found, it returns True; otherwise, it returns False.
not in Operator: This operator checks if a specified value is not present in a sequence. If the value is not found, it returns True; otherwise, it returns False.

my_list = [1, 2, 3, 4]
print(2 in my_list)  # Output: True
print(5 not in my_list)  # Output: True

my_list = [1, 2, 3, 4]

print(2 in my_list) # Output: True

print(5 not in my_list) # Output: True

12. Write a program to count the number of vowels in a string.

def count_vowels(s):
    vowels = "aeiouAEIOU"
    count = 0
    for char in s:
        if char in vowels:
            count += 1
    return count

# Example usage
string = "Hello, World!"
print(count_vowels(string))  # Output: 3

def count_vowels(s):

vowels = "aeiouAEIOU"

count = 0

for char in s:

if char in vowels:

count += 1

return count

# Example usage

string = "Hello, World!"

print(count_vowels(string)) # Output: 3

15.Write a program using a function to find the sum of any numbers passed to the function.

def sum_numbers(*args):
    return sum(args)

# Example usage
print(sum_numbers(1, 2, 3, 4))  # Output: 10
print(sum_numbers(5, 10, 15))   # Output: 30

def sum_numbers(*args):

return sum(args)

# Example usage

print(sum_numbers(1, 2, 3, 4)) # Output: 10

print(sum_numbers(5, 10, 15)) # Output: 30

16 . How do you draw multiple plots in a single figure using Matplotlib?

import matplotlib.pyplot as plt

# Create a 2x1 grid of subplots
plt.subplot(2, 1, 1)  # First subplot
plt.plot([1, 2, 3], [4, 5, 6])
plt.title('First Plot')

plt.subplot(2, 1, 2)  # Second subplot
plt.plot([1, 2, 3], [10, 20, 30])
plt.title('Second Plot')

plt.tight_layout()  # Adjust the layout
plt.show()

import matplotlib.pyplot as plt

# Create a 2x1 grid of subplots

plt.subplot(2, 1, 1) # First subplot

plt.plot([1, 2, 3], [4, 5, 6])

plt.title('First Plot')

plt.subplot(2, 1, 2) # Second subplot

plt.plot([1, 2, 3], [10, 20, 30])

plt.title('Second Plot')

plt.tight_layout() # Adjust the layout

plt.show()

17. Write a program to check if a number entered is prime or not.

def is_prime(number):
    if number <= 1:
        return False
    for i in range(2, int(number**0.5) + 1):
        if number % i == 0:
            return False
    return True

# Example usage
num = int(input("Enter a number: "))
if is_prime(num):
    print(f"{num} is a prime number.")
else:
    print(f"{num} is not a prime number.")

def is_prime(number):

if number <= 1:

return False

for i in range(2, int(number**0.5) + 1):

if number % i == 0:

return False

return True

# Example usage

num = int(input("Enter a number: "))

if is_prime(num):

print(f"{num} is a prime number.")

else:

print(f"{num} is not a prime number.")

18.Explain match-case statement with a suitable example.

The match-case statement, introduced in Python 3.10, is similar to a switch-case statement found in other languages. It allows you to match patterns in a value or object and execute code blocks based on those patterns

def identify_animal(animal):
    match animal:
        case "dog":
            return "It's a dog!"
        case "cat":
            return "It's a cat!"
        case _:
            return "Unknown animal"

# Example usage
print(identify_animal("dog"))  # Output: It's a dog!
print(identify_animal("bird")) # Output: Unknown animal

def identify_animal(animal):

match animal:

case "dog":

return "It's a dog!"

case "cat":

return "It's a cat!"

case _:

return "Unknown animal"

# Example usage

print(identify_animal("dog")) # Output: It's a dog!

print(identify_animal("bird")) # Output: Unknown animal

List comprehension is a concise way to create lists in Python. It allows for the generation of lists based on existing lists, and it can include a conditional statement for filtering.

# Traditional way to create a list of squares
squares = []
for i in range(10):
    squares.append(i ** 2)

# List comprehension
squares = [i ** 2 for i in range(10)]

print(squares)  # Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

# Traditional way to create a list of squares

squares = []

for i in range(10):

squares.append(i ** 2)

# List comprehension

squares = [i ** 2 for i in range(10)]

print(squares) # Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

Method overriding occurs when a subclass provides a specific implementation for a method that is already defined in its superclass. The overridden method in the subclass has the same name, parameters, and return type as the method in the superclass.

class Animal:
    def speak(self):
        return "Some sound"

class Dog(Animal):
    def speak(self):
        return "Woof!"

# Example usage
animal = Animal()
dog = Dog()

print(animal.speak())  # Output: Some sound

class Animal:

def speak(self):

return "Some sound"

class Dog(Animal):

def speak(self):

return "Woof!"

# Example usage

animal = Animal()

dog = Dog()

print(animal.speak()) # Output: Some sound
