What causes this unintentional infinite loops in my code in Python 2.7?

Question

What is the cause of unintentional infinite loops in my code in Python 2.7 but in Python 3.5 gives me error message?

Python 3.5 gives TypeError: unorderable types: str() > int(), How should I resolve it?

Program

condition = '2'

while condition > 5:

    print 'test'

Answer 1

You're trying to compare '2' (a string) to 5 (an int). You should declare without quotes:

condition = 2
