How to force restart kernel

[Stack CopyrightX]

The Canopy python IDE has a simple command (Ctrl+.) that is reached using the menus with Run->Restart Kernel...

This forces the IDE to keep history and things like that, but to restart the python kernel (would it also be correct to say the python interpreter? or is kernel different from interpreter in this context?) so that all existing variables in memory and function definitions are flushed, allowing me to start with a clean kernel.

Is there some way to do this in Spyder?

I have been using Spyder, and using IPython as default. I use Ctrl+. and it do the same thing.

Actually this is a IPython command:

http://ipython.org/ipython-doc/stable/interactive/qtconsole.html

Process Management

With the two-process ZMQ model, the frontend does not block input during
execution. This means that actions can be taken by the frontend while
the Kernel is executing, or even after it crashes. The most basic such
command is via ‘Ctrl-.’, which restarts the kernel. This can be done in
the middle of a blocking execution. The frontend can also know, via a
heartbeat mechanism, that the kernel has died. This means that the
frontend can safely restart the kernel.

The kernel they are referring to is the IPython kernel.

Yes, enter Ctrl + . in the IPython console.

Thank you. This worked for me. I didn't realize it was an IPython command. I did try Ctrl+. in Spyder before posting here, but I guess the focus must not have been in the IPython window because nothing happened the first time I tried it.
