如何在Spyder中使用可选参数执行? [英] How to execute with optional argument in Spyder?

问题描述

我不知道如何在Spyder上执行带有可选参数的程序.我知道如何将变量传递给它，但是我的程序使用argparse，并且我想使用"-h"或"--help"选项执行它，代码如下.

I don't know how to execute a program with optional arguments on Spyder. I know how to pass variables to it, but my program uses argparse, and I want to execute it with the "-h" or "--help" option, the code is the following one

import argparse
parser = argparse.ArgumentParser()
parser.parse_args()

目前，它仅具有默认的可选参数"-h"/-help"，我尝试将其放在命令行选项"上，但不起作用.

For now, it only has the default optional argument of "-h"/"--help", I tried putting it on "Command line options" but it doesn't work.

推荐答案

您必须定义参数才能使用它们.看起来它只是使用默认的argparse方法，该方法仅在构造函数中定义了help方法.

You would have to define the arguments in order for them to be used. It looks like it is just using the default argparse method which only defines the help method in the constructor.

在此处检查文档: https://docs.python.org/3/library/argparse.html

这是解析我之前使用过的args的示例方法:

Here is an example method for parsing the args I have used before:

import argparse


def process_args(source=None):
    parser = argparse.ArgumentParser(prog='my-awesome-program')
    parser.add_argument('--value1', dest='value1', type=str)
    parser.add_argument('--value2', dest='value2', type=str)

    args = parser.parse_args(source)
    return args


def main():
    args = process_args()
    args = vars(args)

    my_value_1 = args['value1']
    my_value_2 = args['value2']
    print('%s, %s' % (my_value_1, my_value_2))


if __name__ == '__main__':
    main()
