python - 如何从python中的字符串中删除反斜杠

问题描述

如果我使用替换功能，那么我也会收到错误消息。

filename = input("copy the file path with it's name and extension and paste it here to Encrypt: ")

filename_replace = filename.replace('\ ', " ")

错误说：

Anomalous backslash in string: '\ '. String constant might be missing an r prefix.

标签： python

解决方案

您需要将反斜杠转义为\\.

filename = input("copy the file path with it's name and extension and paste it here to Encrypt: ")
# say it's something like "c:\myfiles\test.txt"
filename_replace = filename.replace("\\"," ")
# becomes "c: myfiles test.txt"
