flog = open('test.txt', 'r')
flogLines = flog.readlines()
strlist = ['SUCCESS', 'Done','SUCCESSFUL']
res = False
for line in flogLines:
     for fstr in strlist:
         if line.find(fstr) != -1:
            print('found') 
            res = True


if res:
    print('res true')
else: 
    print('res false')

为了增加regex的多样性:

import re

if any(re.findall(r'a|b|c', str, re.IGNORECASE)):
    print 'possible matches thanks to regex'
else:
    print 'no matches'

或者如果你的列表太长- any(re.findall(r'|'.join(a)， str, re.IGNORECASE))

为了提高速度，我会使用这样的函数:

def check_string(string, substring_list):
    for substring in substring_list:
        if substring in string:
            return True
    return False

如果a或str中的字符串变长，您应该小心。简单的解决方案是O(S*(A^2))，其中S是str的长度，A是A中所有字符串长度的总和。要获得更快的解决方案，请查看用于字符串匹配的Aho-Corasick算法，该算法在线性时间O(S+A)内运行。

这取决于上下文 假设你想检查单个文字(任何单个单词a,e,w，..等)就足够了

original_word ="hackerearcth"
for 'h' in original_word:
      print("YES")

如果你想检查original_word中的任何一个字符: 利用

if any(your_required in yourinput for your_required in original_word ):

如果您想要original_word中的所有输入，请使用所有输入 简单的

original_word = ['h', 'a', 'c', 'k', 'e', 'r', 'e', 'a', 'r', 't', 'h']
yourinput = str(input()).lower()
if all(requested_word in yourinput for requested_word in original_word):
    print("yes")

a = ['a', 'b', 'c']
str =  "a123"

a_match = [True for match in a if match in str]

if True in a_match:
  print "some of the strings found in str"
else:
  print "no strings found in str"
