As we know, there are few versions of Arcgis (9.x,10) and Python(2.x,3.x) are in use. Issues are facing when we run scripts/toolbox of arcgis since the script written in one version of python and the python installed with arcgis is different version.
Q1) How to identify python script version so that we can directly execute and save time? Q2) How to convert the existing python script to the installed python version on the system and get result without hassle of programing? Q3) Is there any procedure for arcgis to take python version 2/3.x as default so that, we can install multiple versions of python and change default version to run according to our requirement?
