This bug report is incoherent. This has nothing to do with alarms or regular expressions, and I don't know what your code is supposed to do or what results you are expecting. What's "a calci programe"?

You ask: 

"Do we have any ways to rectify the same. if so please let me know."

First of all, rectify *what*? I don't understand what problem you think you are having. And secondly, this is for reporting bugs in the Python interpreter and libraries, not for asking for help with bugs in your own code.

I'm going to close this bug report now. If you believe it is actually a bug in the interpreter, then please explain what behaviour you expect and show the exact behaviour you get, including any traceback. COPY AND PASTE the code and any errors, don't summarise them or retype them from memory.

If you want help with your own code, I suggest:
