How to clear variables in ipython?

Question

Sometimes I restart the script inside the same ipython session and I get nasty surprises when the variables have not been cleared. How to clear all variables? And is it possible to force it somehow every time I call the magic command% run?

%reset seems to clear certain variables.

In iPython, you can remove the single variable, like this:

Answer 4

Adding the following lines to a new script will clear all variables each time the script is re-run:

 from IPython import get_ipython get_ipython().magic('reset -sf') 

To make life easy, you can add it to your default template.

In Spyder: Tools>Preferences>Editor>Edit template
