Either open the shelve with writeback=True or rewrite the entry.
Rewriting the entry isn't hard: you can just re-use the same value:
def changevalue():
for key in mytest.keys():
temp = mytest[key]
temp.param3 = "newvalue"
mytest[key] = temp
If you really are changing every item in the shelve using writeback=True
will be much simpler, but if you are only changing a few then just tell the
shelve that you've updated them as above.
