change backslash into slash in a path

[paul18fr]

Yes I understand, but there's also another difference: you've add the "r" in front of the string to declare a "regular expression" whereas in my case I'm using a variale: how can I use a variable or how can I declare the variable as a regular expression?

path = 'D:\My Directory1\bin'
Var = r''+ path   #Var = r'' + str(path)
print("using replace", Var.replace('\\', '/'))
print("using replace with raw string", path.replace(r"\ "[0], "/"))
print("using regex", re.sub('\\\\', '/', path))

(obviously it does not work because of \b as it has ever been sugested)
