What's with the underscore(_) ????

[Alfredo P. Ricafort]

Hi,

Look at the following codes:

# file s1.py
import gettext
f=gettext.gettext
_=gettext.gettext


# file test.py
from s1 import *

print f('Hello')
print _('Hello')

Please explain to me why the 2nd print would fail with an error
'NameError: name '_' is not defined'.

Tks.
