installing python 3

[Ashley Forman]

Hello,
  My name is Ashley Forman, and I am emailing because I cannot install
python onto my Mac laptop! I have installed Active-TCl 8.5 along with
Python 3.3 and tried with 3.4, and couldn't figure out a solution to my
problem. When I click on IDLE to open, it does not open at all. Therefore,
if you have any information that could help me, then I would really
appreciate it! Thank you!
Best,
Ashley Forman
