just when think i'm starting handle django start reading 2 scoops of django advise use cookiecutter instead of regular django-admin startproject. authors of 2 scoops big on virtualenv. i've been using anaconda because everywhere says it's better virtualenv. i'm tempted rid of anaconda , use virtualenv try work, figured i'd ask here first. anybody know how cookiecutter work anaconda??? i think you're bit confused anaconda , virtual environment is. @ end of day, both python installations (hopefully) include binaries needed run code. the answer question use virtual environment, not anaconda project, store dependencies in requirements.txt file has project base code can install exact dependencies needed project virtual environment . so, difference? anaconda python bunch of preinstalled libraries geared towards data analysis. means programmer don't have worry installing matplotlib, pandas, or plethora of other libraries. includes binary executes
