在Python中，如果我将字符串分割开，如何检查字符串的每个部分是否为整数

Question

例如，如果我的输入是“ 1 2 3”，如何检查每个部分是否为整数而不是其他任何内容，如果还有其他内容，则可以再次输入字符串，以使其正确无误，否则它将无法继续

Answer 1

>>> s = "1 2 3"
>>> all([i.isdigit() for i in s.split()])
True

>>> l = "1 b 2 5 c"
>>> all([i.isdigit() for i in l.split()])
False

Answer 2

The following reads from standard input and keeps reading until a string is received with space-separated integers. Finally it prints that it got all integers:

s = raw_input('Enter your input:')
while not all((p.isdigit() for p in s.split(" "))):
    print("Not all integers")
    s = raw_input('Enter your input:')
print("Got all integers!")

Answer 3

You can split you string to a list using list1=s.split()

And then check wether each of them is a integer or not.

Answer 4

Ugly code, but it does what you want:

import re
integers = re.compile('[^\d\s]')
while True:
    s = input("Enter integers: ")
    if not integers.match(s):
        break
