This is a great use for a custom generator:

Python 2:

def char_range(c1, c2):
    """Generates the characters from `c1` to `c2`, inclusive."""
    for c in xrange(ord(c1), ord(c2)+1):
        yield chr(c)

then:

for c in char_range('a', 'z'):
    print c

Python 3:

def char_range(c1, c2):
    """Generates the characters from `c1` to `c2`, inclusive."""
    for c in range(ord(c1), ord(c2)+1):
        yield chr(c)

then:

for c in char_range('a', 'z'):
    print(c)
