contemporary python (nested scopes):
def test(data,pre,post):
p = re.compile("([0-9])")
def repl(m):
return pre + m.group(1) + post
print p.sub(repl, data)
old python (object binding):
def test(data,pre,post):
p = re.compile("([0-9])")
def repl(m, pre=pre, post=post):
return pre + m.group(1) + post
print p.sub(repl, data)
