本文主要是介绍jupyter 外部参数报错 keyerror，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
同样的带有传参的python脚本文件放在在pycharm和cmd 运行没问题，放在jupyter 莫名的报错错误如下：
KeyError Traceback (most recent call last)

解决问题方法：
将mian函数里参数判断：
if len(argv[1:]):
user_list = argv[1:]
else:
user_list = []
修改为：
if len(argv[1:])==True:
user_list = argv[1:]
else:
user_list = []
