An infinite loop keeps running because its condition remains true. In Python, while True is the clearest form; execution must reach break, usually after a successful guess or another explicit exit condition. section 2.3
Use an explicit exit path and guard the work performed on each iteration:
- Put repeated input or processing inside while True. section 2.3
- Test for the condition that ends the task, then use break to leave the innermost loop. section 2.3 section 5.9
- Validate or convert input before comparing or storing it; invalid rainfall input uses continue to begin the next iteration. section 2.3 section 5.9
- Watch transformations that revisit inserted characters, such as adding ub before every vowel, because the loop can process its own output. section 3.11
Guess-until-correct
A guessing program generates an answer with random.randint, then enters while True. Each iteration reads input, converts the returned string with int, compares the result with answer, and uses break when the guess is correct. Without that break, the prompt continues indefinitely. section 2.3
while s = input('Enter thoughts:'):
print(f'Your thoughts are: {s}')
Compare a condition-controlled while loop with while True: the former exits when input becomes empty, while the latter requires an explicit break. section 2.3
