How do I add variables to a directory in python

Question

Hello there I have this code:

login=os.getlogin()
if not os.path.exist("C:\Users\login\Documents")

As you can see I have a login variable that gets the user of the computer but I am struggling to use it in the ''if not os.path.exist'' statement, The output I want is for python to get the username of the user and use it in a directory.

Thanks in advance!

You can use string formatting:

if not os.path.exists("C:\Users\{0}\Documents".format(login)):

Or you can build up the string by yourself:

if not os.path.exists("C:\Users\\" + login + "\Documents"):

or if by using join:

if not os.path.exists(os.path.join("C:/", "Users", login, "Documents"):

As already indicated by comments, you should also have a look on this question. This shows you how to properly get the login name.

Note that `os.path.join` is the safest way to generate portable paths. – filippo Jul 01 '18 at 07:28

Note there is a mistake in the second example- the second \ escapes the closing `"`. – Dillon Davis Jul 01 '18 at 07:40
You can also use f-strings, and the old % syntax instead of `.format()` as well. – Dillon Davis Jul 01 '18 at 07:41

@DillonDavis exactly the kind of mistake `os.path.join` is useful to prevent – filippo Jul 01 '18 at 07:47
