>>> parser = argparse.ArgumentParser(description='Process some integers.') ArgumentParser 对象包含将命令行解析成 Python 数据类型所需的全部信息。 添加参数 给一个 ArgumentParser 添加程序参数信息是通过调用 add_argument() 方法完成的。通常,这些调用指定 ArgumentParser 如何获取命令行字符串并将其转换为对象。
使用argparse 的第一步是创建一个 ArgumentParser 对象: >>> >>> parser = argparse.ArgumentParser(description='Process some integers.') ArgumentParser 对象包含将命令行解析成 Python 数据类型所需的全部信息。 添加参数 给一个 ArgumentParser 添加程序参数信息是通过调用 add_argument() 方法完成的。通常,这些...
We've brought back a positional argument, hence the complaint. 注意顺序无关紧要。 How about we give this program of ours back the ability to have multiple verbosity values, and actually get to use them: import argparse parser = argparse.ArgumentParser() parser.add_argument("square", type=int...
pass ... >>> function(0, a=0) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function() got multiple values for keyword argument 'a' 当**name存在表单的最终形式参数时,它接收包含除了与形式参数相对应的所有关键字参数的字典(参见映射类型 - 字典)。
Parsing the command-line arguments is another important step in any CLI app based on argparse. Once you’ve parsed the arguments, then you can start taking action in response to their values. In your custom ls command example, the argument parsing happens on the line containing the args = ...
