python2版本：
L = range(1, 101)
print L[:10]
print L[2::3]
print L[4:50:5]
python3版本：在python3中range的实现变了，并不是返回一个list类型，而是返回一迭代对象。
L= list(range(1, 101))
print(L[:10])
print(L[2::3])
print(L[4:50:5])
L = range(1, 101)
print L[:10]
print L[2::3]
print L[4:50:5]

本题调用有误导,输入average()时返回结果是0.0而不是0.
def average(*args):
if args==():
return 0.0
else:
return sum(args*1.0)/len(args)
print (average())
print (average(1, 2))
print (average(1, 2, 2, 3, 4))
def average(*args):
if args==():
return 0.0
else:
return sum(args*1.0)/len(args)
print (average())
print (average(1, 2))
print (average(1, 2, 2, 3, 4))
