@KevinWheeler Why not just use os.environ and pass it as string?

We just have to take your word that a function used by millions of programs "doesn't work"? | |

a more scalable `run` syntax (single string, many args) is with `shell=True` + non-trivial example

Added more details with demo codes, tips, security implications, and notes for latest python syntax versions such as 3.5+.

Many arguments version looks like that: subprocess.run(["balcon.exe","-n","Tatyana","-t", "Hello world"])

@KevinWheeler You should NOT use shell=True, for this purpose Python comes with os.path.expandvars. In your case you can write: os.path.expandvars("$PATH"). @SethMMorton please reconsider your comment -> Why not to use shell=True

@KevinWheeler You'll have to use shell=True for that to work.

Is there a way to use variable substitution? IE I tried to do echo $PATH by using call(["echo", "$PATH"]), but it just echoed the literal string $PATH instead of doing any substitution. I know I could get the PATH environment variable, but I'm wondering if there is an easy way to have the command behave exactly as if I had executed it in bash.
