response comment

ipython not necessary, make life easier. use command prompt , not familiar installing packages pycharm or anaconda.

if pip installed, , windows environmental variable not set, can still use pip.

1) open windows command prompt administrator 2) navigate python installation ( default directory c:\python27 ) 3) navigate scripts folder (default dir c:\python27\scripts) 4) type 'pip'

5) type 'pip freeze' see packages installed pip. note: pip not keep track of packages installed conda

if able complete steps, changing path variable include scripts directory allow run pip typing 'pip' anywhere.

to install ipython: command prompt administrator rights: 'pip install ipython[all]'
