[Tutor] Executing a command from a specific directory

[Ansuman Dash]

Hi,

I have written it like that. It is like press 1 and it ll download file1 and
press 2 it ll download file2 etc....

But my question was I am using "time.sleep()" to make my script to wait for
the file download and then validate it in log file, so is there any other
way I can synchronize my code with the download.

I am asking this because some files are very huge (120MB) and download also
depends on N/W bandwidth so sometimes it ll be done in 30mins and some times
it takes 60 mins. So I can't rely on "time.sleep()"

Thanks,
Ansu
