Running Bash commands in Python

Question

On my local machine, I run a python script which contains this line

bashCommand = \"cwm --rdf test.rdf --ntriples > test.nt\"
os.system(bashCommand)
         


        

Answer 1

subprocess.Popen() is prefered over os.system() as it offers more control and visibility. However, If you find subprocess.Popen() too verbose or complex, peasyshell is a small wrapper I wrote above it, which makes it easy to interact with bash from Python.
