[Python] Strange behavior when using ctypes to cast/mutate the memory of a number in Python

I was just reading about using the ctypes module in Python to cast interned integers to behave like different values. So I had the following code:



ctypes.cast(id(1), ctypes.POINTER(ctypes.c_int))[6] = 2

print(1) # Prints: 2
print(1 + 1) # Prints: 2 Why?


Why does the second line print 2 also if 1 is now behaving like 2? (Other numbers to the same thing.)

Thanks!
