Explain the Python While Loops with example.

Question

Anubhav Kumar · Answer

A while loop keeps running as long as a condition is
True.
It’s useful when you don’t know in advance how many times you need to loop.
Syntax
while condition:
    # code block
condition → a Boolean expression (True or 
False)The loop continues until the condition becomes False
Examples
1. Basic while loop
i = 1
while i andlt;= 5:
    print(i)
    i += 1   # increase i
Output:
1
2
3
4
5
2. Infinite loop (careful!)
while True:
    print("This will run forever!")
    break  # use break to stop it
3. Using break
i = 0
while i andlt; 10:
    if i == 5:
        break
    print(i)
    i += 1
Output:
0
1
2
3
4
4. Using continue
i = 0
while i andlt; 6:
    i += 1
    if i == 3:
        continue
    print(i)
Output:
1
2
4
5
6
5. While loop with else
i = 1
while i andlt;= 3:
    print(i)
    i += 1
else:
    print("Loop finished!")
Output:
1
2
3
Loop finished!
Key difference between for and while:
for → best when you know how many times you want to repeat.while → best when you repeat until a condition changes.
