Python interpreter, virtual environments and pycharm

Question

Platform Windows. IDE PyCharm CE.

I have a script that uses module ArcPy from ESRI. This module has its own Python 2.6. I have to import a module that uses dictionary comprehensions not supported by Python 2.6.

How do I work around this without rewriting the code to avoiding list comprehensions?

Other questions:

• What should be the correct pattern for project creation and interpreter maintenance? Should I always use virtual dedicated envs for each project importing any needed modules and keep isolation for each?

• Is it correct to import the extra needed packages for my projects to the ArcPy python installation Python 2.6.5 (C:/Python26/ArcGIS10.0/python.exe)? Can this cause problems later to arc map?

Answer 1

You can upgrade your ArcGis Python 2.6 release to 2.7. If you need Python 3, it won't work, because arcpy works only in Python 2.
