This specific one is easy, though this doesn't generalize:
import string
print string.lowercase + string.uppercase

You could abuse __getitem__ (terribly, heh!) and use slice syntax...
class crange():
def __init__(self):
self.valid = range(47,58) + range(65,91) + range(97,123)
def __getitem__(self, s):

Thanks for you quick reply.
I didn't know any string constants.

The concatenation of the strings lowercase and uppercase described below.
The specific value is locale-dependen

That makes sense. 100% agree with you.

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)

you might consider this cheating, but it's packed with zen goodness:
>>> import string
>>> print string.letters
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
