You can have loops inside loops, known as nested loops. A for or while loop can contain another loop inside it.

Example:

for i in range(1, 4):
    for j in range(1, 4):
        print(f"i = {i}, j = {j}")

Output:

i = 1, j = 1
i = 1, j = 2
i = 1, j = 3
i = 2, j = 1
i = 2, j = 2
i = 2, j = 3
i = 3, j = 1
i = 3, j = 2
i = 3, j = 3

Real-world Example:

Vasanta Kumar wants to combine different types of beverages with different types of snacks:

beverages = ["Tea", "Coffee"]
snacks = ["Cookies", "Cake"]

for beverage in beverages:
    for snack in snacks:
        print(f"Vasanta Kumar can have {beverage} with {snack}.")

Output:

Vasanta Kumar can have Tea with Cookies.
Vasanta Kumar can have Tea with Cake.
Vasanta Kumar can have Coffee with Cookies.
Vasanta Kumar can have Coffee with Cake.
