I want to know why Pycharm does not show the methods of a class by pressing control + spaço. IDE's usually show all methods present in the class. In the image below I show you what IDE suggests to me of methods for any class.
I was able to solve my problem by updating the Python interpreter inside Pycharm.
1) First click on the top tab in File -> Settings.
2) I clicked Project: untitled - > Project interpreter - > Show All ..
3)Thenextstepwastoenteraddinterpreter(+).
4)Finally,IenteredtheVirtualenvEnvironment,IselectedNewenvironment,IselectedthePythoninterpreterinBaseinterpreter.ThenIcheckedtheoptionsandclickedOk.
Pycharm made some updates to the interpreter, and when it finished, started to show all methods belonging to the class. The process is the same on both Linux and Windows.
