Macs normally ship with Python installed already, version 2.7.

If you need a specific version, for example Python 3, you can fetch installers 
for the current versions here:

  3.4.3:  https://www.python.org/downloads/release/python-343/
  2.7.10: https://www.python.org/downloads/release/python-2710/

Generally you execute python code from the command line by handing it the 
filename or module name, eg:

  python filename.py
  python -m module.name

You will need a text editor. There are any number of things.

Regarding the transfer, your raspberry should have an ethernet socket. You'll 
need to plug it into your network. Then you can scp the files to the raspberry 
without mucking around with SD cards.

I cannot help you with these. What degree of programming knowledge or 
experience do you have?

Download links above. You will have to pick an editor. The Mac offers the 
textedit app and the usual command line based editors. Make sure you're using a 
text editor, which makes plain text files. Not a word processor.

Start by making sure you have a working Python. Write an utterly trivial Python 
program and run it. For example, make a file "foo.py" containing:

  print("Hello world!")

and run it:

  python foo.py
