python - How can I find the path for an executable?

Question

I need to setup environment with the path to a binary. In the shell, I can use which to find the path. Is there an equivalent in python? This is my code.

cmd = ["which","abc"]
p = subprocess.Popen(cmd, stdout=subprocess.PIPE)
res = p.stdout.readlines()
if len(res) == 0: return False
return True

Answer 1

There is distutils.spawn.find_executable().
