Creating Symbols From Usage
Suppose you are referring a class or a method that has not yet been created. With PyCharm, you can easily stub out the missing symbol with the aid of the dedicated intention action.
To create a symbol from usage, follow these general steps
Type the name that references a non-existent symbol. PyCharm highlights the reference.
Press Alt+Enter, and choose the corresponding option from the suggestion list, for example Create class <class name>, or Add method <method name> to class <class name>.
