Also note that instead of combining things by yourself, you can use
the os.path.join function. It takes any number of arguments and will
automatically add in the right separator. Ex. os.path.join("usr",
"local", "MyDirectory", "MyFile") will spit back
"/usr/local/MyDirectory/MyFile" on Linux.
It you have to write some code that deals with files and directories,
you should never need an if statement checking for platform. Use the
Standard Library and you won't regret it.
