I have installed Python 2.7 (Windwos 7). However, I am unable to load the GUI. I get no response when I try to open. I re-installed it but again the same problem. What might be the solution?
If you have python in the default installation path, try in the windows shell:
C:\Python27\pythonw C:\Python27\Lib\idlelib\idle.pyw
or change the path accordingly. This should work even if you have other conflicting pythons in your installation or paths are not set.
