You say you're a beginner. If so, you shouldn't be trying to use
threads, which are tricky. I've been programming for 46 years, and I
seldom have had to write multi-threading code.
But this looks like a school assignment. And it looks like the code has
little to do with the assignment. So let's break down the assignment a bit.
Your assignment says the two threads will be called thread1 and thread2.
So why do you call them t1 and t2?
Your assignment says the two functions will be called func1 and func2.
So why do you call them print_time and print_time1 ?
The assignment doesn't say anything and about running an external
process. Since that's also complex and error prone, perhaps you should
keep it simple till everything else works.
Some general principles:
1) try not to do the same thing in several places. You create threads
in 3 places, and two of them are wrong or at least non-optimal. Keep
just the one where you do it right.
2) Use useful names for the various variables. Except of course where
the assignment specifies the name to be used. Then use that name.
3) Learn one new concept at a time. If you're concentrating on threads
here, don't try to learn subprocess at the same time, unless that's what
the assignment calls for.
4) Avoid chdir, especially in multithreaded programs. Use an absolute
path if you must when dealing with files. Except for trivial programs,
changing the working directory is likely to bite you in the foot
somewhere else in the program.
