ipython notebook clear all code

Question

All I want to do is try some new codes in ipython notebook and I don't want to save it every time as its done automatically. Instead what I want is clear all the codes of ipython notebook along with reset of variables.

I want to do some coding and clear everything and start coding another set of codes without going to new python portion and without saving the current code.

Any shortcuts will be appreciated.

Note: I want to clear every cells code one time. All I want is an interface which appears when i create new python file, but I don't want to save my current code.

Answer 1

In Jupyter, do the following to clear all cells:

1. Press Esc to enter command mode.
2. Hold Shift. Select the first and last cells to select all cells.*
3. Press d twice to delete all selected cells.

Alternatively, if you simply want to try out code, consider running the ipython console, which is purely interactive in the REPL and does not require creating a new file. In a command prompt, type:

> ipython
