How do I iterate over a list in a hash in Python?

Question

I want to get the elements of the array SIZE from the A_TABLE, just like it shows in the top part below, but with an iterator, as I totally failed to do in the bottom part. New to Python about one hour ago, and I'll keep looking, but any suggestions appreciated.

SIZE   = ('too small', 'just right', 'too large')

A_TABLE = {}
A_TABLE['size'] = SIZE
print "size is " + A_TABLE['size'][0]
print "size is " + A_TABLE['size'][1]
print "size is " + A_TABLE['size'][2]

for x in A_TABLE['size'][x]:
    print "size is " + A_TABLE['size'][x]

Your print statements show that you are using python2. If you are "new to python," you should be learning python3, not python2. Python2 is rapidly approaching end of life. — John1024

You're looping in the wrong way, here's how you should do it:

SIZE = ('too small', 'just right', 'too large')

A_TABLE = {}
A_TABLE['size'] = SIZE

for x in A_TABLE['size']: # change here
    print "size is " + x  # and here
