是否可以使用python将打印输出保存在字典中? [英] Is it possible to save the print-output in a dict with python?

问题描述

我想知道，是否可以将这段代码的输出保存到字典中(也许这也是错误的数据类型).我还没有编码方面的经验，所以我想不出它可以工作的方式. 我想创建一个字典，其中包含txt.-file的行以及相应行的值.最后，我想创建一个代码，用户可以选择通过输入在行中搜索单词-输出应返回相应的行.有没有人建议?提前致谢！干杯！

I want to know, if it's possible to save the output of this code into a dictionary (maybe it's also the wrong data-type). I'm not expirienced in coding yet, so I can't think of a way it could work. I want to create a dicitionary that has the lines of the txt.-file in it alongside the value of the corresponding line. In the end, I want to create a code, where the user has the option to search for a word in the line through an input - the output should return the corresponding line. Has anyone a suggestion? Thanks in advance! Cheers!

filepath = 'myfile.txt'  
with open(filepath) as fp:  
   line = fp.readline()
   cnt = 1
   while line:
       print("Line {}: {}".format(cnt, line.strip()))
       line = fp.readline()
       cnt += 1

推荐答案

这应该做到(使用您作为框架提供的代码，只需要多一行即可将其存储在字典中):

This should do it (using the code you provided as a framework, it only takes one extra line to store it in a dictionary):

my_dict={}

filepath = 'myfile.txt'  
with open(filepath) as fp:  
   line = fp.readline()
   cnt = 1
   while line:
       # print("Line {}: {}".format(cnt, line.strip()))
       my_dict[str(line.strip())] = cnt
       line = fp.readline()
       cnt += 1

然后，您可以提示用户输入，如下所示:

Then, you can prompt for user input like this:

usr_in = input('enter text to search: ')

print('That text is found at line(s) {}'.format(
                  [v for k,v in my_dict.items() if usr_in in k]))
