Python从两个文件的嵌套循环中读取行 [英] Python reading lines in nested for loops from two files

问题描述

我想逐行将一个文本文件的行与另一个文本文件进行匹配，嵌套的for循环有问题，它一定很简单，但我找不到它，

I want to match the lines of one text file with another text file, line by line, there is a problem with my nested for loops, it must be simple, but I can't find it,

for line1 in ratings:
    cont1+=1

    for line2 in movies:
         cont2+=1
         print(cont1,cont2)

我通过此循环对其进行了简化，以检查错误， 外部循环未达到cont = 2

I simplified it with this loops, to check the error, The outer loop doesn't reach cont=2,

1 1
1 2
1 3
1 4
1 5
1 6
1 7

推荐答案

问题是，由于每个人的答复，我需要使用seek(0)重置内部循环，以确保循环正常进行.

The problem is that I need to reset the inner loop with seek(0), doing that the loop works properly, thanks to everyone for your replies.
