for Loop in Python

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

? Basic Syntax:

for item in sequence: # code block

? Examples

???? 1. Loop through a list

fruits = ['apple', 'banana', 'cherry'] for fruit in fruits: print(fruit)

???? 2. Using range()

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

???? 3. Using range(start, stop, step)

# Print even numbers from 2 to 10 for i in range(2, 11, 2): print(i)

???? 4. Loop through a string

for char in "Python": print(char)

???? 5. Nested for loop

for i in range(1, 3): for j in range(1, 4): print(i, j)

???? Tip:

You can use break, continue, or else with for loops.

???? Example with break:

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

???? Example with continue:

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

???? Example with else:

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