Python argparse module Python argparse module is the preferred way to parse command line arguments. It provides a lot of option such as positional arguments, default value for arguments, help message, specifying data type of argument etc. At the very simplest form, we can use it like below. ...

print('The command line arguments are:') for i in sys.argv: print(i) Python顶部模块 Python的getopt模块通过参数验证扩展了输入字符串的分隔。基于getopt C函数, 它允许长短选项, 包括值分配。 与解析命令行参数的C getopt()函数非常相似。 它在解析命令行参数时非常有用, 我们希望用户在此输入一些选项。

Whilesys.argvis a straightforward way to grab command-line arguments, it can get messy when you start dealing with multiple arguments, optional arguments, and flags. That’s where argparse comes in. Argparse: Simplifying Command-line Parsing ...
Usually, for all optional arguments, we provide the long option and sometimes also the short option. Then we can access the value provided from the command line using the long option as the key (with the hyphen replaced with an underscore or the single-character short option as the key if...
