Any executable script can be run in PyCharm. You don't need to create any run/debug configuration in advance. A temporary run/debug configuration is already created for you.
To run any script without creating a run/debug configuration, do one of the following:
Right-click an open file in the editor and then choose Run <filename> from the context menu.
For the main clause, click the icon in the gutter, and then choose Run <script name>.
