How to use Python to call exe with parameters

Preface

In actual production and life, the exe packaged by others is often used. If there are a bunch of files to be processed, all of which rely on manual input, is it a waste of time. This blog post will briefly introduce how to call exe with python.

exe file structure

The two files mainly used are exe and config, as shown in the following figure:

Code

The main process is to pass parameters first, then call exe

import os
import glob
import subprocess

def polygonize(imagePath, raster_path, forest_shp_path, pwd):
    # pwd = ''
    os.chdir(os.path.realpath(os.path.join(pwd,'polygonize/')))
    polygonize_exe = os.path.realpath(os.path.join(pwd,'polygonize/polygonize0529.exe'))
    polygonize_path = os.path.realpath(os.path.join(pwd,'polygonize/polygonize.config'))
    rmHole = "100"
    simpoly = "4"
    scale = "3"
    with open(polygonize_path,'w') as f_config:
        f_config.write("--image=" + imagePath+'\n')
        f_config.write("--edgebuf="+raster_path+'\n')
        f_config.write("--line="+forest_shp_path+'\n')
        f_config.write("--rmHole=" + rmHole + '\n')
        f_config.write("--simpoly=" + simpoly + '\n')
        f_config.write("--scale=" + scale)
    f_config.close()
    subprocess.call(polygonize_exe)
