🔁 Loops (for/while)

# Range se loop
for i in range(5):
    print(i, end=" ")  # 0 1 2 3 4

# List ke items par

for fruit in fruits:
    print(f"🍎 {fruit}")

# range(start, stop, step)
for i in range(1, 11, 2):
    print(i, end=" ")  # 1 3 5 7 9

n = 1
while n <= 5:
    print(n, end=" ")
    n += 1  # 1 2 3 4 5

# User input loop

    print(f"Tumne likha: {word}")

for i in range(10):
    if i == 5:
        break       # loop band karo
    print(i, end=" ")  # 0 1 2 3 4

for i in range(5):
