Question

我正在尝试在字符串上出现单词时打印，但实际上它不会打印任何内容。我的文本文件是：

words={'apple', 'banana', 'pie'}
strings={'Hello World!', 'I love pie', 'Ate an apple'}

with open("words.txt") as words_file: with open("strings.txt") as strings_file: all_strings = list(map(str.strip,strings_file)) for a_string in all_strings: for word in words_file: if word in a_string: print a_string

，输出就像

吃了一个苹果

我爱馅饼

Answer 1

from itertools import izip
with open("file1.txt") as f1:
    with open("file2.txt") as f2:
         for f1_line,f2_line in izip(f1,f2): #this will return the same lines from both files
             do_something(f1_line,f2_line)

你一遍又一遍地看到同样的事情的原因是你

  for line2 in file2:
      print line1.split() # line 1 will not change until you go through every line in file2

[edit]如评论中所述，如果你使用的是python2.7 +，你可以将文件开放合并为一行

with open("file1.txt") as f1, open("file2.txt") as f2:
         for f1_line,f2_line in izip(f1,f2): #this will return the same lines from both files
             do_something(f1_line,f2_line)

下面的代码可以做你想要的......

from itertools import izip
with open("words.txt") as words_file:
    with open("strings.txt") as strings_file:
        all_strings = list(map(str.strip,strings_file))
        for word in words_file:
        for a_string in all_strings:
           if word in a_string:
              print a_string

同时迭代两个文件，并将字符串与字符串PYTHON进行比较
