first of all, your code can be shortened to

import webbrowser, sys
 
urls = {'prod':'https://produrl', 'uat':'https://uat', 'sit':'http://sit',
        'dev':'http://dev', 'reftest'='http://reftest', 'refqa':'http://refqa'
        'refdev':'http://dev'}
 
if len(sys.argv) == 1:
    print ('W parametrze musisz podać nazwę środowiska...')
else:
    arg = sys.argv[1].lower()
    url = urls.get(arg, None)
    if url:
        webbrowser.get(webbrowser.iexplore).open_new_tab(url)
        print ('Otwieram {}...'.format(arg))
    else:
        print ('Nie znam takiego środowiska {}...'.format(arg))

not sure if it will work but you may try to use some of the modules like pywinauto, pyautogui
