Use Python to launch Excel file

Question

when i try os.system("open " + 'myfile.xlsx')
i get the output '0'

similarly, trying
os.system("start excel.exe myfilepath")
gives the result 32512

I have imported os and system, and I'm on mac. How can I change this so it does actually launch that excel file? And out of curiosity, what do the numbers it prints out mean?

Thanks!

Answer 1

Just these two lines

import os
os.system("start EXCEL.EXE file.xlsx")

Provided that file.xlsx is in the current directory.
