Python For Loop

← Previous Next →

The for loop in Python is used to iterate over a sequence (like a list, tuple, string, or range).

🔹 Syntax

for variable in sequence:
    # code block

🔹 Looping Through a List

fruits = ["apple", "banana", "cherry"]

for fruit in fruits:
    print(fruit)

🔹 Looping Through a String

for letter in "Python":
    print(letter)

🔹 Using the range() Function

for i in range(5):
    print(i)

Output:
0 1 2 3 4

🔹 Specify Start and End in range()

for i in range(2, 6):
    print(i)

Output:
2 3 4 5

🔹 Using Step in range()

for i in range(1, 10, 2):
    print(i)

Output:
1 3 5 7 9

🔹 Else in For Loop

for i in range(3):
    print(i)
else:
    print("Finished")

🔹 Nested For Loop

colors = ["red", "green"]
objects = ["car", "bike"]

for color in colors:
    for obj in objects:
        print(color, obj)

🔹 Break Statement

for i in range(5):
    if i == 3:
        break
    print(i)

🔹 Continue Statement

for i in range(5):
    if i == 2:
        continue
    print(i)

🧪 Test Yourself with These Examples

Practice using for loop with range, lists, strings, and control flow.
