Re: [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.

try putting an "r" in front of the string, i.e. os.system (r'C:.....).

you mentioned "it doesn't work."  what do you mean by that?  in other
words, what did the Python interpreter do...  give an error, nothing,
etc.?

thanks,
