Fire up a python console in the browser
PyConsole is an extension which you can use to directly run python programs in the browser; It mimics the behavior of a normal REPL that you can launch in a terminal but aims to achieve more with the power of the browser environment.
You can import popular data analysis libraries such numpy and pandas for data wrangling or just write normal python snippet for day to day tasks. You can even create beautiful visualizations directly in the console using the matplotlib / plotly library.
Caveat: Due to the fact this is still in beta version, expect things to break once in a while. (We are hoping as browser becomes more mature. This should become less and less frequent :)
1. In case you encounter a dead session, try start a new session by clicking the > icon. It will maintain all information from the current session.
2. Delete commands you don't like any more by clicking the trash icon to keep the session clean.
