| The result of: import struct struct.calcsize('cd') #returns 16 appears to be incorrect. The correct result should be 1 + 8 = 9. | ||

| No, the result is correct as it stands. If you define struct Foo{ char c; double d; }; on your system, and then compute sizeof(struct Foo) using the C compiler, it will tell you that the struct is 16 bytes in size. Read some text about alignment and padding. |
