1:为什么sum=0.0,不能是0, 2:为什么两个return不是对齐的,不太明白
def average(*args):
sum=0.0
if len(args)==0:
return sum
for x in args:
sum=sum+x
return sum/len(args)
print average()
print average(1, 2)
print average(1, 2, 2, 3, 4)
def average(*args):
sum=0.0
if len(args)==0:
return sum
for x in args:
sum=sum+x
return sum/len(args)
print average()
print average(1, 2)
print average(1, 2, 2, 3, 4)
