我的parseTwoPoleBreakers
功能有问题。我正在尝试将一个列表inputList
输入到该函数中,因此我知道在该列表中放置brk1_int_c,brk1_ext_c,brk2_int_c,brk2_ext_c
的位置。运行NameError: global name 'brk1_int_c' is not defined
下面的脚本时出现以下错误。我很确定我使用行global brk1_int_c,brk1_ext_c,brk2_int_c,brk2_ext_c
定义我的变量,但我可能错了,所以关于如何定义这些变量并进入列表inputList
的任何输入都将非常感激。

如果它应该是“全局的”,你可能必须先在文件中直接定义它,而不是在函数中。
尝试在代码文件的开头添加类似内容:
brk1_int_c = ''
brk1_ext_c = ''
brk2_int_c = ''
brk2_ext_c = ''
