Pycharm配置运行参数设置，这参数怎么设置呢？

问题描述：

答

命令行传参，运行时你需要将设定的相应参数传递进命令行中才可以。在代码中有二两处要改一下，一是在84行，for c in xrange(len(scheme)),xrange函数是python2中的函数，如果你运行python3的话，将其改为range()函数。二是在第72行和第85行两处构造字符串列表时写法不正确，用python3中的f-string进行改写。在运行时，输入图片放在imgs文件夹根目录，参数file_pattern,用已有文件的名，不带后缀名，test为输出文件子目录，假如有图片wcb1.jpg,wcb.jpg2,那么用命令test_color.py --in_dir imgs --file_pattern wcb --file_indices 1 2 --out_subdir test,即可运行。修改的代码如下，供你作参考并加以修改完善。

你用sys.argv获取命令行参数列表，看看能不能成功获取，如果能获取，说明你代码的获取方式有问题
