How to replace backslash with forward slash - Python

Question

I wrote this simple little program:

def main ( ):
    with open("test.txt", "rt") as fin:
        with open("out.txt", "wt") as fout:
                for line in fin:
                    fout.write(line.replace("\", "/"))
    print ("done")
main ()

I know that "" is an escape literal in Python but all I need is to scan through the text file and replace every single backlash with a forward slash "/".

Anyone knows what to do?

You have to remember that strings in python are interpreted. Only raw strings do not follow this rule. Here I mean that if for example you have a "\n" included in your string, it would be interpreted as a new line. Fortunately strings read from file are already raw.

All you have to do is simply use the regular expression:

s.replace('\\','/')

You know how to replace '\"' by 'somestring' as in ... 'hello \" to replace'.replace('\"', '\\"') ... This does not seem to work.

Use cascade of replacements: 'hello \" to replace'.replace('\\', '').replace('"', '')
