Python module --- argparse argparse是python用于解析命令行参数和选项的标准模块,用于代替已经过时的optparse模块。argparse模块的作用是用于解析命令行参数,程序只需定义好它要求的参数,然后argparse将负责如何从sys.argv中解析出这些参数。argparse模块还会自动生成帮助和使用信息并且当用户赋给程序非法的参数时产生错误信息...
$ python3 prog.py4Traceback(most recent call last):File"prog.py", line5,in<module> print(args.square**2)TypeError: unsupported operandtype(s)for**orpow():'str'and'int' 这样直接进行操作会发生错误,因为模块默认将输入的参数识别为string类型,我们只有明确表明为int型才可以进行**操作。
