python怎么用input函数输入一个列表

>>> x=input
>>> 123
123

>>> x=input()
1,2,3,4
>>> xlist=x.split(",")
>>> print(xlist)
['1', '2', '3', '4']

>>> x=input()
1,2,3,4
>>> xlist=x.split(",")
>>> print(xlist)
['1', '2', '3', '4']
>>> xlist = [int(xlist[i]) for i in range(len(xlist))] #for循环，把每个字符转成int值
>>> print(xlist)
[1, 2, 3, 4]

>>> x=input()
1 2 3 4
>>> xlist=x.split(" ")
>>> print(xlist)
['1', '2', '3', '4']
>>> xlist = [int(xlist[i]) for i in range(len(xlist))]
>>> print(xlist)
[1, 2, 3, 4]
