In python, how do u do a format check? I need to do a specific format check that ensures that the data entered is in the format NX OR NNX, where N is a number that is 7, 8, or 9, and NN is a number that is 10 or 11, and X is a letter from A to F ( basically should be 7A - 7F, 8A-8F and so on until 11F. Thanks.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
