1) PyDeque also has __copy__ function. Should I remove that too? 
   If I remove that function, I will get errors in test cases.
   So Should I modify the test case file? 

2) When are we going to introduce the __copy__ function in jython?
   It is because CPython supports that. Any .py file which uses this
   __copy__ func will not work on the jython, isn't it?

3) When I tried with passing key's string value, some of the test 
   cases are getting failed. I revisited the CPython code. It
   seems like key itself is passed to be printed.

4) I couldn't find the place where I missed braces. I will be happy if
   you show me where it is.

Please clarify me.
