I have the following function: def phone_found(p): for c in contacts: if p in c: return True return False
with the following test data: contacts = ['672.891.7280 x999', '291.792.9000 x111'] main = ['291.792.9001', '291.792.9000'] which works: filter(phone_found, main) # ['291.792.9000'] My attempt at a lambda function fails: filter(lambda p: (p in c for c in contacts), main) # ['291.792.9001', '291.792.9000'] Besides using a lambda ;) , what have I done wrong? -- ~Ethan~ -- https://mail.python.org/mailman/listinfo/python-list
