Just copy/paste the following source code to a file and run it:
<code>
sourceCodeToExecute = """
dict1 = { 1:23, 2:76, 4:56 }
dict2 = { 23:'A', 76:'B', 56:'C' }
# How do I get a dictionary that is
dict3 = { 1:'A', 2:'B', 4:'C' }
dict4 = {}
for key in dict1.keys():
dict4[key] = dict2[dict1[key]]
#:for
print 'dict3 == dict4 is', dict3 == dict4
"""
print
print ' execution of following source code: '
print
print '"""',
print sourceCodeToExecute
print '"""'
print
print ' results in output of: '
print
exec(sourceCodeToExecute)
</code>
The core idea of an inner join:
dict2[dict1[key]]
Hope this helps inspite of the fact there is some more complicated code
involved, which I provided to show the beauty of Python from the point
of view of my own style of writing 'tutorial-like' code which explains
itself by its output.
