Question

这应该验证一行中有一个IP，然后打印该行，但我正在接收

TypeError: unsupported operand types for 'list' & 'int'

我想不出我现有代码的解决方案，有人可以帮忙吗？

import sys

import re
match = 0

def CheckIP(ip, filter):

    match = re.compile(b"^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$", ip)
    if match == None:
        print ("No IP's in this file!")
        sys.exit(0)
    else:
        pass

with open('text.log') as f:

    x=[]
    count = 0
    for l in f:
        x = l.strip().split("\t")[5:8] # Grab the elements you want...
        x.pop(1) #... but remove the element you don't
        CheckIP(x, match)
        print(" ".join(x)) # Now print them
        print('\n')
        count += 1
        if count == 20:
                print("\n\n\n\n\n-----NEW GROUPING OF 20 RESULTS-----\n\n\n\n\n\n")
                count = 0

print(count)

修改：

import sys
import re

with open('text.log') as f:

    x=[]
    count = 0
    for l in f:
        x = l.strip().split("\t")[5:8] # Grab the elements you want...
        x.pop(1) #... but remove the element you don't
        match = re.compile("^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$", x)
        if any(lambda s: match.search(s) for s in x):
            pass
        else:
            print ("No IP's in this file!")
            sys.exit(0)
        print(" ".join(x)) # Now print them
        print('\n')
        count += 1
        if count == 20:
                print("\n\n\n\n\n-----NEW GROUPING OF 20 RESULTS-----\n\n\n\n\n\n")
                count = 0

print(count)

您未正确使用re.compile。第二个参数应该是由按位“或”re个标志组成的整数，而不是要匹配的字符串列表。

执行您尝试执行的操作的最简单方法是：

pattern = re.compile(  ### regex ### )
if any(pattern.search(s) for s in ip):
    pass
else:
    print ("No IP's in this file!")
    sys.exit(0)

TypeError：'list'和＆amp ;;不支持的操作数类型“诠释”
