The for loop iterates over all the numbers in range(10)
, that is, [0,1,2,3,4,5,6,7,8,9]
.
That you change the current value of i
has no effect on the next value in the range.
You can get the desired behavior with a while loop.
i = 0
while i < 10:
# do stuff and manipulate `i` as much as you like
if i==5:
i+=3
print i
# don't forget to increment `i` manually
i += 1
