The program is an illustration of recursive functions in Python;

Recursive functions are functions executed from within itself

<h3>The python program</h3>

The program written in python, where comments are used to explain each action is as follows:

#This defines the function

def revStr(myStr):

   #This returns an empty string if the string is empty

   if myStr == "":

       return myStr

   #If otherwise, this returns the reversed string recursively

   else:

       return revStr(myStr[1:]) + myStr[0]

Write the code for invoking a method named sendObject. There is one argument for this method which is of type Customer.Assume th
Dafna1 [17]

Answer:

sendObject(John_Doe)

Explanation:

To invoke a method, simply call the name of the method, followed by it's arguments in parenthesis. i.e methodname(argument).

In this case, the name of the method is sendObject and it's argument is a Customer object stored in or referenced by a variable John_Doe.

The above is true since the method is defined in the same class that calls it. Otherwise, it is not valid.
