If so, then hit. You can also configure completion by using either jedi or rope as a backend to either CompanyMode or AutoComplete. One of the major benefits of using Emacs over a Python-specific IDE is the ability to work in other languages. The GUD also connects pdb to the actual source file in the bottom window, which tracks your current location. Since IPython 5 it has a new terminal interface, which is not compatible with Emacs’ inferior shells. python-x also provides some additional features, python-cell provides Matlab-like cells in python buffers.
