change backslash into slash in a path

[deanhystad]

There is no need to replace "\" with "/". str objects never contain escape sequences. A backslash in a string is just a backslash. Escape sequences only exist in string literals, strings that are hardcoded in your program.

This program's problem happened when the Python code is compiled.

path = "D:\My Directory1\bin"  # Contains escape sequence \b
print(path, path.replace("\b", r"\b"))

Output:
D:\My Directoryin D:\My Directory1\bin

When Python compiled "Path = 'D:\My Directory1\bin'" it converted the "\b" to a backspace character (ASCII control character BS). The resulting string was 'D:\My Directory1<BS>in' where <BS> is the backspace character. At no point does the path str include a "\b" escape sequence, so it would be impossible to replace the "\b" with "/b". The path str does include a backspace character and you can replace that character a "\b" string. There is no reason to do this, but it is possible.

Thing learned here:
1. You cannot replace escape sequences in a str object because str objects do not contain escape sequences.
2. Escape sequences are converted to characters when Python compiles your program.
3. You don't have to worry about backslashes in input strings. In a str a backslash is just a backslash.
