Hello, any ideas why this does not work?
def add(key, num):
... a[key] += num ...
a={} a["007-12"] = 22 if not a.has_key("007-12") else add("007-12",22) a
{'007-12': 22} # OK here, this is what I want
a["007-12"] = 22 if not a.has_key("007-12") else add("007-12",22) a
{'007-12': None} # why does this became None?
Thanks
