Pythonista is tied with Pycharm as my favorite python IDE on any platform! – Pythonista 3 Review

Pythonista is truly a full featured python development environment and I wish that it were available on more platforms. It is awesome to work with and adds a lot of value to iOS devices. It is a must have for anyone who would like to utilize the power of python while on the go.
