Python IDE for teaching?

PyDev is a Python IDE for Eclipse, which may be used in Python, Jython and IronPython development.

Reference: PyDev

Also you can use PySide - it includes GUI programming

Update:

So, as I searched around, I found some Python IDEs with integrated gui builder, such as:

Visual Tkinter Python IDE

Monkey Studio

and other ones (please look at the bottom of the page at the section: IDEs with integrated gui builder)

Update 2:

I lately started using PyCharm and I can tell it is very complex IDE and has a lot of features (I was very familiar with the interface of the IDE, since I use for Java development IntelliJ IDEA which is basically from the same company), so I would recommend to anyone to use it.

For more related to Python IDEs, please look at this question. It covers in detail almost each Python IDE for its important features: What IDE to use for Python?

You have to try PyScripter:

• Fast IDE
• Very small memory foot-print
• Intuitive interface

• Free & it's open-source!
