在python中找到一个文本文件在另一个文件中的条目 [英] Find entries of one text file in another file in python

问题描述

我有两个文件。文件 A 每行都有一些条目，我需要确定在文件 B 中是否找到任何条目。这是我的脚本（使用两个函数）：

I have two files. File A has some entries in each line and I need to find if any entry is found in File B. Here is my script (using two functions):

def readB(x):
 with open('B.txt') as resultFile:
    for line in resultFile:
        if x in line:
            print x


def readA():
 with open('A.txt') as bondNumberFile:
    for line in bondNumberFile:
        readB(line)

readA()

此脚本在第二个文件中找到第一个条目，然后找不到下一个。

This script finds the first entry in second file and then does not finds the next one. What might be wrong here?

文件A看起来像这样：

122323 
812549
232335
921020

文件B看起来像这样：

696798  727832  750478  784201  812549  838916  870906  890988  921020  
697506  727874  751037  784955  813096  838978  872494  891368  921789  
696798  727832  750478  784201  812549  838916  870906  890988  921020  
697506  727874  751037  784955  813096  838978  872494  891368  921789  

推荐答案

将换行符的条带化

读取行时Python包含换行符-您的第一个条目读为 1223232\n 。删除换行符，它将起作用。

Strip the entries of newlines

Python includes newlines when you read lines - your first entry is read as 1223232\n. Strip the newline and it will work.

def readA():
    with open('A.txt') as bondNumberFile:
        for line in bondNumberFile:
            readB(line.rstrip())
