What does '$', '.', '/' and '& means in this succession? Note: 12:34
PM is a argument to the yourfile.py.
"$" is the shell prompting you to let you know it's ready for you to
type a command.
"./" says "look in the current directory for a file called ...".
Since the first token in the command contains a path separator ("/") the
normal mechanism of looking for the executable in each of the
directories in the current $PATH is not used [if you don't understand
this sentence, ignore it].
"&" says "run this command in the background and immediately prompt for
another command, instead of waiting for the command to finish like you
usually do".
Technically, by the way, 12:34 PM is *two* arguments to the yourfile.py,
not one.
