why cant we put a decimal in the for range in python

Question

For example, I put this:

for i in range (2,n**0.5+1,2):

      print(i)

And it doesn't work. I tried putting 1/2 instead but it didn't work I have python 3.6

Because the function isn't designed to accept non-integer arguments. — juanpa.arrivillaga, Mar 17 '17 at 21:02
`help(range)` at the console can give you information such as @juanpa.arrivillaga provided — Charlie G, Mar 17 '17 at 21:10

Unfortunately, range only accepts integers. But you can use this function instead:

def frange(start, stop, step):
    current = start
    while current < stop:
        yield current
        current += step

Note that this is likely to run a step more or less than you intended, due to floating-point inaccuracies. – jasonharper Mar 17 '17 at 21:03
Thanks for your answer, but unfortunately i haven't learned that function yet, therefore, im not allowed to use it – python-help Mar 17 '17 at 21:04
