Floating point math? I thought, historically at least, that bc is built

A PEP is necessary if the proposed change is contentious. If there is
widespread agreement that the change is desirable, no PEP is needed.

Hello guys,
I need to detect the newline characters used in the file I am reading.
For this purpose I am using the following code:

fobj.readlines()

Is PEP necessary to add a new package to the standard library?
What if the community just wants to add a new module to an existing package?
What if only a new function has to be added to a module in the standard library?
What if only a line or two are to be added to a function in the

I think you need an explicit cast:
