Is it possible to make a letter range in python?

Question

Is there a way to do a letter range in python like this:

for x in range(a,h,)

Answer 1

You can use ord() to convert the letters into character ordinals and back:

def char_range(start, end, step=1):
    for char in range(ord(start), ord(end), step):
        yield chr(char)

It seems to work just fine:

>>> ''.join(char_range('a', 'z'))
    'abcdefghijklmnopqrstuvwxy'
