Infinite Loops in Python: Causes and Fixes
An infinite loop runs forever, consuming CPU until the process is killed. They are caused by a loop condition that never becomes false or missing increment logic.
❌ Infinite While Loop
count = 0
total = 0
while count < 10:
total += count
# Bug: count is never incremented!✅ Fixed Loop
count = 0
total = 0
while count < 10:
total += count
count += 1 # Ensures loop terminates
print(total)💡
Pro tip: Prefer for loops over while when the number of iterations is known. Add a max_iterations safety counter for complex termination conditions.
