None of those three "statements" make sense to me.  Could you translate, 
or elaborate?  And fix typos?

What OS is this running on?

Is the process a program called grep.exe?  Or a second Python program? 
Who's doing the grep, that separate program or your original one?

Define Apply.  What's it mean to apply a string to a command?

What's an "is pattern" ?  And who's looking for it?

What's the real goal?  Or is this just a paraphrasing of an arbitrary 
school assignment (which don't always make sense).

Sure, nothing in that description implies threads, just a separate 
process.  No idea why that's simpler, though.
