I'm using Spyder 2.2.5 with Python 2.7 and I want the editor to display the arguments of the function I'm calling after I type the first parenthesis. I know it's possible, because I can see it in the video-tutorials I'm using. I've tried (at least I think so..) all menu-items. Getting crazy here, please help!
You can activate the object inspector to display the documention of the function itself by enabling automatic connections for your editor or console. It will then show you the function parameters as you press the left parenthesis.
To enable it go to Tools > Preferences > Object Inspector . Under Help-> Automatic connections check your desired programming environment and enable plug-in.
