When you need to install the python module:
# -*- coding: utf-8 -*-
# ver 2019.03.27
import imp
import os
packages=['selenium','ctypes','time','os','shutil','subprocess','unittest','urllib','cow']
for p in packages:
not_installed = "'%s'"%p
print("Module %s"%not_installed,)
try:
fp, pathname, description = imp.find_module(p)
imp.load_module(p, fp, pathname, description)
except:
print("FAIL, RUNNING AUTOMATIC INSTALLATION")
module_to_install = not_installed[1: -1]
setup_module='python -m pip install ' + module_to_install
print(setup_module)
os.system(setup_module)
continue
finally:
print("OK")
