Or do this:
def translate(text):
import string
all=string.maketrans('','')
badcars=all.translate(all,string.letters+string.digits)
table=string.maketrans(badcars,'_'*len(badcars))
return text.translate(table)
No pollution.

Then after you are finished with the bindings, delete them:
import string
all=string.maketrans('','')
badcars=all.translate(all,string.letters+string.digits)
table=string.maketrans(badcars,'_'*len(badcars))
def translate(text):
return text.translate(table)
# clean up the temporary variables so as to prevent namespace pollution
del string; del all; del badcars; del table
