反斜杠和\\ xnnn转换为ascii

Question

I am reading from a file the path for some jpg files and the format is:

...
prc103\CV137\2018\09\14\21\103137435939720180914210353_F01.jpg
prc103\CV137\2018\09\14\21\103137435940120180914210820_F01.jpg
prc103\CV137\2018\09\14\21\103137435946020180914215915_F01.jpg
...

I want to change some characteristics of this path but when I try to manipulate the string I have no success because it changed to this:

'prc103\\CV137\x818\x009\x0c\x11C137435939720180914210353_F01.jpg'

How to have the original clean ascii string ?

Answer 1

From the documentation on "Lexical analysis" :

The backslash () character is used to escape characters that otherwise have a special meaning, such as newline, backslash itself, or the quote character.

You can find more examples of such "escape sequences" in the documentation or see for yourself by opening a Python shell (ie typing in \\2018 , which will return \\x818 , as in your example).

Is the file you're reading accessible to you? Try to find and replace the backslashes in your text file with forward slashes.
