On the other hand, the “is” operator in Python verifies whether the two variables point to the same object in the memory. In general, programmers use “==” and “!=” operators to compare values. Suppose, x=1 y=2 z=2 (x==y) will return false as both are assigned different ...

The "SyntaxError: Missing parentheses in call to 'print'" error message is raised when you are using Python 3 and you have forgotten to include the parentheses when calling the print() function.
Python >>>add_one=add_lib.add_one>>>add_one.argtypes=[ctypes.POINTER(ctypes.c_int)] In this code, you’re setting the function signature to match what C is expecting. Now, if you were to try to call this code with the wrong type, then you would get a nice warning instead of ...
