In a language that defines Names that are bound to objects, there can't be
a 'type' inferred.  In C or similar, when you delcair the variable you are
setting aside the memory to hold something of that type.  This is compile
time typing.  That isn't how python works, so naming something an int will
never make it an int.  intMe = 'Joel' is totally valid in python.

Sticking to ideas like this will hinder understanding of how python works.
I suggest taking two hours to study the python documentation at python.org.
I don't speak Chinese, but I know that I can't just use a dictionary of
English to Chinese and use the same syntax.  It won't be Chinese.

Get over your prejudice and learn the new language.... or don't, but trying
to shoe horn python into the concepts of another language won't help you
understand python, it will produce ugly, messy, unsupportable code.
