You don't have to do it that way, no.

In general, when opening a file, you can do it two ways: Either provide
a full pathname, or provide a relative pathname.

If you provide a full pathname (for example "/usr/home/smith/myfile.txt"),
that file will be opened and it does not matter what the current working
directory is.

If you provide a relative pathname (for example "myfile.txt"), python
will attempt to open that file starting from the current working dir.
