Programming applications

[etam]

For some reason I can't open the programming applications from the menu on my pi even though I have done previously. I can access python in the terminal by typing in 'python3' but I want to open the idle.

I get a long list of error ending with "This probably means that tk wasn't installed properly".

Any ideas what's going on?

A post with those errors would probably be very en-lighting to us.

It can be everything from bad powersupply ( not very likely) or a bad SD card ( more likely ) to some read-errors in the filesystem or some failed upgrade.

Getting the Pi connected to the internet so you can do "sudo apt-get update" and "sudo apt-get upgrade" is probably a good idea.
Taking a backup of files/projects you are working on or other important files is also a good great idea.

This probably means that tk wasn't installed properly.
