Python read file - pass variable name [duplicate]

Question

Very simple question for Python 2:

I am calling specific library/function passing filename with readonly flag:

myfunction(r'/tmp/file.txt')

I wanted to replace it with variable:

filename = '/tmp/file.txt'
myfunction(r????)

How can I call that function?

Answer 1

That is not readonly flag. That means raw string. You use it when you don't want escape sequences inside string to be interpreted (like \n, \t etc.) See https://docs.python.org/2.0/ref/strings.html

For your string, you don't need it since it does not contain any escape sequence. Just omit the leading r.
