def average(*args):??? t=len(args)??? sum = 0.0??? if t==0.0:??????? return 0.0??? else:??????? for x in args:??????????? sum+=x??????? return sum/tprint average()print average(1, 2)print average(1, 2, 2, 3, 4)
你傳值了嗎？？
你調用函數了嗎？？？
def average(*args):
????if not len(args): ??return 0.0
????s = 0.0
????for i in args:
????????s = s + i
????return s*1.0/len(args)
print average()
print average(1, 2)
print average(1, 2, 2, 3, 4)
這樣可以了 ，得用for遍歷args
'return' outside function
len(args)!=0
