Yes, managing char ranges is a bit of pain with Python.
You can also pack those chars:
xcrange = lambda cc: (chr(c) for c in xrange(ord(cc[0]), ord(cc[1])
+1))
But I don't like that much.
The calls:
''.join(xcrange('az')) + ''.join(xcrange('AZ'))
But note that you return the last item of the range too, and that goes
against the semantic of the usual Python range/xrange, so you may want
to call this function with another name.
Maybe there are better ways to solve this problem. Maybe a way to
generate (closed?) char ranges can be added to the Python standard
lib.
