通过python文件的Robot框架的命令行参数

我想从命令提示符处将参数传递给python文件变量，然后通过将python文件添加为变量来从机器人文件中打印相同的参数。

cmd (Variables) --> python file --> robot (print those variables) 但是，显然没有一项尝试能取得预期的结果。任何指导将不胜感激。

注意： Robot和Python文件都在pycharm IDE中位于同一目录下。

命令行：-

1st try: robot -d Report -V test.py Test_sample.robot|py test.py test@test.com test@123 QA1

2nd try: robot -d Report Test_sample.robot|py test.py test@test.com test@123 QA1

3rd try: robot -d Report --Variablefile py test.py Test_sample.robot|py test.py test@test.com test@123 QA1

4th try: robot -d Report -V | py test.py test@test.com test@123 QA1| Test_sample.robot

蟒蛇：-

import sys

username = str(sys.argv[1])
password = str(sys.argv[2])
environment = str(sys.argv[3])
机器人：-

*** Settings ***
Library     SeleniumLibrary
Library     Collections
Variables  test.py

*** Test Cases ***
Pass variables from Python File

        log to console  The usr is: "${username}"
        log to console  The pwd is: "${password}"
        log to console  The env is: "${environment}"

预期：

usr是：test@test.com pwd是：test @ 123环境是：QA1

实际：
