python: os.system does not execute shell comand
- by capoluca
I need to execute shell command in python program (I have ubuntu). More specifically I want to create graph using graphviz in python script. My code is
os.system("dot -Tpng graph.dot -o graph.png")
It does not work, but if I just type dot -Tpng graph.dot -o graph.png in command line then everything is fine. Do you know what the problem? Thank…
