python引用另一个文件中的列表_使用一个文件在Python中搜索另一个文件中的行

这应该行。我使用了您提供的两个示例数据文件，下面的代码提供了您发布的所需输出。如果这个过程要经常重复，并且您需要加快速度，那么您可能需要考虑使用不同的搜索算法。如果是这样的话，请告诉我最常见的操作是什么(插入列表、搜索列表、删除列表中的项目)，然后我们可以使用最合适的搜索算法。在# open the list of words to search for

list_file = open('list.txt')

search_words = []

# loop through the words in the search list

for word in list_file:

# save each word in an array and strip whitespace

search_words.append(word.strip())

list_file.close()

# this is where the matching lines will be stored

matches = []

# open the master file

master_file = open('master.txt')

# loop through each line in the master file

for line in master_file:

# split the current line into array, this allows for us to use the "in" operator to search for exact strings

current_line = line.split()

# loop through each search word

for search_word in search_words:

# check if the search word is in the current line

if search_word in current_line:

# if found then save the line as we found it in the file

matches.append(line)

# once found then stop searching the current line

break

master_file.close()

# create the new file

new_file = open('new_file.txt', 'w+')

# loop through all of the matched lines

for line in matches:

# write the current matched line to the new file

new_file.write(line)

new_file.close()
