file "<stdin>", line 2
print(I)

please help me

Answer 1

you didnt even define what "I" is

Answer 2

bardya, you cant use a variable without passing a value to it but you can use i in for loops to pass the amount of numbers in an array(etc.) but you didnt use i for anything like that. replace print(I) with print(x) and add line x-=x to make it stop.

Answer 3

i=1
while i<5:
i=i+1
print(i)
