I\'m just starting out learning python with GEdit plus various plugins as my IDE.
Visual Studio/F# has a feature which permits the highlighting on a piece of text in th
I installed iPython console in gedit and do most of my simple scripting in it, but gedit is a very simple editor, so it'll not have some advance feature like an IDE
But if you want code exploring, or auto completion, I recommend a real IDE like Eclipse.
If you just want a editor, KomodoEdit is fine.
What I do is keep a file called python_temp.py. I have a shortcut to it in my dock. I use it as a scratch pad. Whenever I want to quickly run some code, I copy the code, click the shortcut in the doc, paste in the text and hit f5 to run. Quick, easy, simple, flexible.
I think what you're looking for is http://live.gnome.org/Gedit/Plugins/BetterPythonConsole.
You hit F5 and it runs the code in your file in a IDLE-like console. I don't know if it can only run selected code. (I don't think it can) but you can always copy the needed code in a new window and run it from there.
Have a look through the plugin list for other interesting stuff: http://live.gnome.org/Gedit/Plugins
To answer your second question, and hopefully guide you in a direction you'll be happier with, I think you ought to consider trying some different editors. There are many with more powerful code exploration features than GEdit has. Check out this post:
What IDE to use for Python?
Yes, you use "external tools plugin"
As an example,
Close the Preferences Window
Tools > Manage External Tools
.
#!/usr/bin/env python
import sys
result = eval(sys.stdin.read())
print expression, "=>", result, type(result)
.
The closest to a decent IDE... Install gedit-developer-plugins (through synaptic || apt-get) and don't forget to enable (what you need) from gEdit's plugins (Edit->Preferences [tab] plugins) and happy coding
