Running a batch file with parameters in Python OR F#

I searched the site, but I didn't see anything quite matching what I was looking for. I created a stand-alone application that uses a web ser开发者_JAVA百科vice I created. To run the client I use:

C:/scriptsdirecotry> "run-client.bat" param1 param2 param3 param4

How would I go about coding this in Python or F#. It seems like it should be pretty simple, but I haven't seen anything online that quite matches what I'm looking for.

Python is similar.

import os
os.system("run-client.bat param1 param2")

If you need asynchronous behavior or redirected standard streams.

from subprocess import *
p = Popen(['run-client.bat', param1, param2], stdout=PIPE, stderr=PIPE)
output, errors = p.communicate()
p.wait() # wait for process to terminate

In F#, you could use the Process class from the System.Diagnostics namespace. The simplest way to run the command should be this:

open System.Diagnostics
Process.Start("run-client.bat", "param1 param2")

However, if you need to provide more parameters, you may need to create ProcessStartInfo object first (it allows you to specify more options).

Or you can use fsi.exe to call a F# script (.fsx). Given the following code in file "Script.fsx"

#light

printfn "You used following arguments: "
for arg in fsi.CommandLineArgs do
  printfn "\t%s" arg

printfn "Done!"

You can call it from the command line using the syntax:

fsi --exec .\Script.fsx hello world

The FSharp interactive will then return

You used following arguments:
        .\Script.fsx
        hello
        world
Done!
