From the Eric6 Technical Report

Compatibility with Python ver. 3 or/and 2 From the current ver. 6, this same Eric IDE is fully Python 3 or/and 2 compatible, both considered as an executing program and as a developing environment. Indeed this same unique Eric IDE can be used with Python ver. 3 only, OR Python ver. 2 only, or Python ver. 3 AND ver. 2, together. This way offering a unique environment where to attenuate the inconveniences caused by such odd incompatibility between these two consecutive Python versions, and possibly easing the transition between them. That said, we have here decided to adopt and use Python ver. 3—and the consequently related accessories, such as primarily the related PyQt library—as the only base language for this Report 1 , and that for manifest reasons of manageability. Giving thus for granted that a fool-proof compatibility should be experienced in case of adoption of Python ver. 2.
