Answer 1

An infinite loop is a block of code that, intentionally or not, will repeat the execution of the loop body infinitely (never stop). By right, every loop we create must have a final condition, that is a where the requirements to evaluate a condition as true are met, and by then, the loop must cease repetition.

Since you used while true: , your code may become an infinite loop, if it didn't have the condition checking branch, which you did using the following line:
if text == "":
break

The lines above checks whether if the line that's read from the file has any content, and it instructed the loop to stop when a blank line was found (final condition is met)

There is other condition set in the code, that checks if the line read from the file begins with # character, the branch than instructed that the loop to ignore the line, and continue to the next loop iteration:
if text[0] == '#':
continue

Conclusion, without the if text == "": your loop is an infinite loop, it will keep on repeating the instructions, "forever".
