检查给定字符串中是否存在回车 [英] check carriage return is there in a given string

问题描述

我，我正在从文件中读取一些行，我正在检查每一行是否具有 CRLF 的 windows 类型.如果任何行中不存在 '\n' 或 '\r'，则必须报告错误.我尝试使用以下代码，即使该行没有\r"，也不会报告任何错误

i,m reading some lines from a file and i'm checking whether each line has windows type of CRLF or not. If either '\n' or '\r' is absent in any line, it has to report an error. I tried with the below code, even if the line doesnt have '\r', it is not reporting any error

Open_file = open(File_Name,'r').readlines()
while Loop_Counter!= Last_Line:
        Line_Read = Open_file[Loop_Counter]
        if('\r\n' in Line_Read):
            pass
        else:
            print Loop_Counter

谢谢

推荐答案

试试这个

Open_file = open(File_Name,'rb').readlines()

你必须以二进制模式打开文件

you have to open file in binary mode
