Hi , I am trying to merge(I am not sure if that is the right term)
dictionaries like this
dict1 ={'a':4,'b':3,'v':7,'h':4}
dict2={'a':5,'v':4,'k':3}
dict3 would be {'a':[4,5],'b':[3,4],'v':[7,4],'k':[0,3],'h':[4,0]}

Thank you for your explanations and especially your clear examples of a
phenomenon(when list elements are tuples) which takes a few moments of
study to truly grasp.

After much fiddling around, I got 2to3 to work! And it did a fine, if
not perfect job on mycalc.py (which has about 120 functions and 1993
lines).
What I did that worked, was to use the E:\Python26\Tools\Scripts, and

written in 2.x, and are together in one file, mycalc.py.
