Troubles with program

[Harambe]

@Harambe it is recommended you use Python 3 though - Python 2 isn't supported anymore

I wanted to but my iPad has problems with the new version

import random
number=sorted(random.sample(range(1,1501)))
for i in range(100):
   letters=sorted(random.sample('abcdefgh',4))
    print(str(number) + '.' + ' ' + ','.join(letters))

Error in 2nd line. I dont know why. Range command includes start, stop and count value. Didnt write 1 as count cause it is given automatically.
