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

的元素上进行迭代。

a = ['a', 'b', 'c']
str = "a123"
found_a_string = False
for item in a:    
    if item in str:
        found_a_string = True

if found_a_string:
    print "found a match"
else:
    print "no match found"

只是关于如何在String中获得所有列表元素的更多信息

a = ['a', 'b', 'c']
str = "a123" 
list(filter(lambda x:  x in str, a))

如果您想要单词的精确匹配，那么可以考虑对目标字符串进行单词标记。我使用nltk推荐的word_tokenize:

from nltk.tokenize import word_tokenize

下面是接受答案的标记化字符串:

a_string = "A string is more than its parts!"
tokens = word_tokenize(a_string)
tokens
Out[46]: ['A', 'string', 'is', 'more', 'than', 'its', 'parts', '!']

接受的答案修改如下:

matches_1 = ["more", "wholesome", "milk"]
[x in tokens for x in matches_1]
Out[42]: [True, False, False]

在公认的答案中，单词“more”仍然是匹配的。但是，如果“mo”成为匹配字符串，接受的答案仍然找到匹配。这是我不希望看到的行为。

matches_2 = ["mo", "wholesome", "milk"]
[x in a_string for x in matches_1]
Out[43]: [True, False, False]

使用单词标记化，“mo”不再匹配:

[x in tokens for x in matches_2]
Out[44]: [False, False, False]

这是我想要的附加行为。这个答案也回答了这里的重复问题。

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')
