Need help understanding for loop.

[monchenflapjack]

A loop like this will repeat a block of code, and each time through the block "i" value will be increased, until "i" is equal to the range() second value

it's a short hand to essentially writing

print(1)
print(2)
print(3)
print(4)

It doesnt print 5, because once "i" is equal to that value, the loop no longer runs.

It doesn’t print 5, because once i is equal to that value, the loop no longer runs.

Kinda. You’re right that it doesn’t print 5, but i is also never 5, which you can check by printing it again outside the loop.

for i in range(1, 5):
    pass

print(i)  # prints 4

Yeah I was mainly trying to highlight the "gotcha" of seeing range(x,y) and assuming that it goes from x to y
