At the OS level, these two actions are *completely* different. The
webbrowser module launches an entirely separate program in its own
independent process, where the "file browser" is opening a standard
dialog inside of the current process and dependent upon the current
process' message loop. (AFAIK, every GUI environment uses some sort
of message/event loop...)
I don't know Macs, but on Windows, the closest "file browser" parallel
to what the webbrowser module is doing would be
os.system("explorer.exe"), which launches a separate program in an
independent process. However, if you're trying to get the results of
the file selection back into your own app, you need to do the file
browsing within your own process (or explicitly use some form of
inter-process communication). In order to use a GUI file-browsing
dialog, you need to follow all the rules for a GUI program.
