this concept works on boolean
means a thing will executed until something is "True"

means in first condition i=0 then i=2 then i=3

every condition will be checked in the last case when it will check the condition it will return True and the loop will broke

but when if you will do this

while True:
#code

means the condition will go on untill broken by a break statement like this

while True: #code will stop instantly
break
