[New-bugs-announce] [issue12740] Add struct.Struct.nmemb

[Stefan Krah]

New submission from Stefan Krah <stefan-usenet at bytereef.org>:

It is somewhat complicated to calculate the number of members in
a Struct, so I propose to add Struct.nmemb (in 3.3, 3.2 and 2.7):

>>> import struct
>>> s = struct.Struct("Pxx3Lxxxx3s")
>>> s.size
47
>>> s.nmemb
5


I chose 'nmemb' because it is a standard name in Unix man pages.
Another option would be to spell it out ('nmembers').
