I've written a code to check whether python shell is running in 32bit or 64bit. But the code prints 8 instead of 64

Question

print(struct.calcsize("p") * 8)

The above code prints 8 instead of 32 or 64.

Answer 1

According to the docs, you're actually looking for struct.calcsize("P"). Uppercase P is the equivalent of void * in C.
