Quick Example

python
count = 0
while count < 5:
    print(count)
    count += 1

# Sum until threshold
total = 0
n = 1
while total < 100:
    total += n
    n += 1
print(f"Sum reached {total} after adding {n-1} numbers")

while repeats its body as long as the condition is True. Make sure the condition eventually becomes False or you get an infinite loop.
