In a nutshell that means that the numbers seem to be random and can be used for various applications as if they were indeed random, but in fact they are just a really strange series of fixed numbers.
Sometime, for example when you use subprocess you might want to run an external program avoiding the invocation of the shell. For that you need to have the external command in pieces, not in a single long string.
So what if you have the command as a string?
When writing a test or whenn running a build job it is usually a good practice to use a temporary directory and then clean up after the process is done.
It is also a good practice to make sure the temporary directoy is unique so if two processes run at the same time they won't interfere.
