Question

i try to run a program( a stemmer with a tcl file) to read a txt file and save the result into an other txt file. When i run the command through dos-windows terminal it works fine, but when i run this through python terminal with os.system() it returns 1 value and nothing happens..
Here is the code:

>>>import os
>>>os.system('C:\Python27\Lib\site-packages\tclsh.exe -encoding utf-8     C:\Python27\Lib\site-packages\GreekStemmer.tcl in.txt out.txt')
>>>1

I guess ‘1’ means that the command didnt executed succesfully?? And when i run this in dos-terminal it creates the out.txt file with the result.But here not..

Answer 1

On my machine the following doesn’t work, because the backslashes are not interpretted. They indicate special charachters.

import os
os.system('C:\bin\Tcl\bin\tclsh.exe')

You can add an r before the string

import os
os.system(r'C:\bin\Tcl\bin\tclsh.exe')

or use doubled backslases

import os
os.system('C:\\bin\\Tcl\\bin\\tclsh.exe')
