[Tutor] How to check the word size of the platform(OS)?
What is the way to check the word size of the platform(OS), and also int size and character size, are they the same. I searched on line But couldn't get an answer ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I searched on line But couldn't get an answer You need to give us more context. Word size usually depends on CPU architecture. It could be anything from 8 bit to 128 bit (and possibly more). int size and char size depend on the compiler/interpreter. For example in the TinyC compiler both int and char are 8 bits. But several C++ compilers have settings/pragmas so you can change the sizes within the limits of the target CPU. If you are talking about Python (and this is, after all, a Python list!) then int size is effectively unlimited. char size depends on the Unicode encoding you choose. It can be anything from 8 bits to 32 bits What exactly do you need to know? How do you plan on using it? -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I searched on line But couldn't > get an answer You can get some platform details from the platform module: https://docs.python.org/2/library/platform.html but why do you need these details? Python is a high-level object-oriented language, not a low-level language like C, and native machine types aren't very often relevant. For example, Python ints are not the same as native ints, they are "Big Num" objects of unlimited size: py> sys.getsizeof(23) # returns number of bytes used 12 py> sys.getsizeof(2**3) 4014 Just about the only things I can think of where I might want to know these sorts of low-level platform details can be handled by the struct module: https://docs.python.org/2/library/struct.html If you explain what you want to do in more detail, perhaps we can help with a better answer. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
