How can I find the index of a back slash within a string?

Question

f = open("newFile.txt", "w+")
pathName = os.path.abspath(f.name)
index = pathName.find(r"\") <-- This needs fixing

Answer 1

You should use a double backslash, that's all.
...find("\\")

just make sure it is the right slash, as you will encounter the regular one in Linux and in Sololearn most likely.
