Explain the Python For Loops

ICSM 489 24-Sep-2025

A for loop is used to repeat a block of code a specific number of times (iterate over a sequence). It goes through items in a list, tuple, string, dictionary, or any iterable object.

Basic Syntax

for variable in iterable:
    # code bloc

variable → takes the value of each item in the iterable, one at a time
iterable → a collection (like list, tuple, string, range, etc.)

Examples

1. Loop through a list

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

for fruit in fruits:
    print(fruit)

Output:

apple
banana
cherry

2. Loop with `range()`

The range() function generates a sequence of numbers.

for i in range(5):   # from 0 to 4
    print(i)

Output:

3. Loop with start and end in `range()`

for i in range(2, 6):  # from 2 to 5
    print(i)

Output:

4. Loop through a string

for char in "Python":
    print(char)

Output:

P
y
t
h
o
n

5. Using `break` (stop the loop early)

for i in range(10):
    if i == 5:
        break
    print(i)

Output:

6. Using `continue` (skip current iteration)

for i in range(6):
    if i == 3:
        continue
    print(i)

Output:

7. Loop with `else`

Python’s for loops can have an else block that runs when the loop finishes without a break.

for i in range(3):
    print(i)
else:
    print("Loop finished!")

Output:

0
1
2
Loop finished!

So, for loops in Python are very flexible and often used with range(), lists, dictionaries, and strings.
