我想匹配文件中的多个字符串。我如何在python中执行此操作？

目标：匹配两个值为＆＃34; DC1＆＃34; ＆安培; ＆＃34; TIER2＆＃34;来自档案

我的代码，但匹配字符串对象

中的任何字符串

strings = ["DC1","TIER2"]
with open(r"D:\kick-6.log", "r" ) as data:
    for deltaa in data:
        deltaa = data.readline().rstrip()
        print ("*********")
        for item in strings:
            if item in deltaa:
                print (deltaa)

使用all进行检查：

all(iterable)如果iterable的所有元素都为真（或如果iterable为空）。相当于：
def all(iterable):
    for element in iterable:
        if not element:
            return False
    return True

strings = ["DC1","TIER2"]
with open(r"D:\kick-6.log", "r" ) as data:
    for deltaa in data:
        if all(x in deltaa for x in strings): #Check if all items in strings exit in deltaa
            print (deltaa)

如果您想检查strings中是否至少有一个deltaa使用any而是：

any(iterable)如果iterable的任何元素为true，则返回True。如果 iterable为空，返回False。相当于：
def any(iterable):
    for element in iterable:
        if element:
            return True
    return False

strings = ["DC1","TIER2"]
with open(r"D:\kick-6.log", "r" ) as data:
    for deltaa in data:
        if any(x in deltaa for x in strings): #Check if any item in strings exits in deltaa
            print (deltaa)
