A Python script file, function.py, contains only the following lines of Python code.

def my_func(msg): print("Here is the message " + msg) When run, the script prints nothing to the screen and exits. Why?

a.		The defined function is not called, .so the print function is never called.
b.		Function definitions are ignored by Python, like comments.
c.		The script contains a syntax error.
d.		The function is not defined correctly.
