Python .txt 的字符串输入和输出

Question

我正在开发一个聊天机器人项目，该项目通过使用 txt 文件存储输入和输出来模仿用户。但是我遇到了一个问题，它无法正确比较输入和文件。

这里是代码行：

  with open('memory.txt', 'r+') as mem:
#memory.txt is where is store the I/O. ex  "(input)/(output)" helloinput/hellooutput

        for line in mem.read():
#reiterates through each line

            if(UI + '/') in line:
#Here is the problem, where the ui being the user input var is not comparing correct to the memory.txt file line.
#(yes) the / is needed for it to work and i have tried to str(UI + '/') but still no luck 

                print(line.rsplit('/',1)[0])
#this prints out everything after the / character

抱歉，如果问题看起来有点不清楚。

Answer 1

mem.read() 将所有文件作为一个字符串整体读取

您需要使用 mem.readlines()。 readlines 将文件作为行列表读取

或者您可以直接遍历文件指针

for x in mem:             # here x is line
    # do your stuff with line here
