我在10年内没有使用过argparse,但我理解它,以及我在下面的工作,因为我希望它能够工作......但是这将会获得很多随着我继续添加命令,解析器和子分析器而变得更加复杂。我想知道组织这个最好的方法是什么?在我看来,我应该能够看到文本中的命令序列,几乎和我在图表中看到的一样清晰......但是每次看到它,离开一段时间后,我的大脑会游泳,因为我试图遵循它。必须有更好的方式来组织这种权利? Python Argparse,如何正确组织ArgParse代码

的潜在途径,以更好的方式:
- 解析器/子分析器重命名。
- 更改语句的顺序。
- 某种方式来缩进而不与python混淆。
所有的想法都在桌面上,我想看看其他人在设计复杂命令时如何处理这个问题。
我会改变的订购和使用较短的变量名。一旦创建完成,就向分析器添加参数,并为分析器使用简短的通用名称。然后,您可以为每个子分析器重用相同的短名称。 – chepner
