I'm trying to learn Python and am trying to execute a python file in terminal. I'm using 2.7.3 python version on my OS X. I've changed the directory in terminal to where the file is located, but I'm getting an error in terminal:

>>> python ex1.py
  File "<stdin>", line 1
    python ex1.py
         ^
SyntaxError: invalid syntax

The ex1.py file contains:

print "Hello World!"
print "Hello Again"
print "I like typing this."
print "This is fun."
print 'Yay! Printing.'
print "I'd much rather you 'not'."
print 'I "said" do not touch this.'

Any ideas on how to fix this? Thx a bunch.
