[Tutor] about calling external program in Python

[Mu Mu]

Dear all,

I tried the following:

>>> os.system(r'C:\\simulation test\\epanet2d.exe C:\\simulation
test\\Network3_1.inp C:\\simulation test\\Network3_1.out')
1
>>> os.system('C:\simulation test\epanet2d.exe C:\simulation
test\Network3_1.inp C:\simulation test\Network3_1.out')
1
>>> os.system(r'C:\simulation test\epanet2d.exe C:\simulation
test\Network3_1.inp C:\simulation test\Network3_1.out')
1
>>> os.system(r'"C:\simulation test\epanet2d.exe"  "C:\simulation
test\Network3_1.inp" "C:\simulation test\Network3_1.out"')
1

They all returned '1' in the interactive window and gave no result in the
designated output folder. All I saw is a flash of the ms-dos black window
and then disappeared.

I tried ms-dos command line, it works pretty good.

Thanks.
J.
