Create a function and the functionality should it print "Hello Caller"

Certainly! Here is an example of a function in Python that will print "Hello Caller" when called:

def hello_caller():
  print("Hello Caller")

To use this function, you would simply call it by typing hello_caller(). This would execute the code within the function, which in this case is just a single line that prints "Hello Caller".

For example:

hello_caller()

This would output the following:

Hello Caller
