In line 3 of the Conv function, you write "str="The name is" + str .
However, str has yet to be defined, from what I can tell. Thus, Python
should throw a NameError. Unforutnately, you haven't included the
exception that Python gives you with this email, so I can't really
help you much more than that.
To get a value from a dictionary D, simply do:
>>> D = {1:'test', 2:'monkey', 3:'apple'}
>>> D[2]
'monkey'
You should read the Python Tutorial at http://docs.python.org/tut/tut.html .

Send us the exception python gives you and we may be able to help you more.
