For practice, write programs to do the following tasks. Comma Code Say you have a list value like this: spam = ['apples', 'bananas', 'tofu', 'cats'] Write a function that takes a list value as an argument and returns a string with all the items separated by a comma and a space, with and inserted before the last item. For example, passing the previous spam list to the function would return 'apples, bananas, tofu, and cats'. But your func- tion should be able to work with any list value passed to it.

Concept explainers

Concept of flowchart

A flow chart diagram is a collection of symbols that represents the steps involved in a process. It is a generic tool that can be adapted for various purposes. It is one of the most common process analysis tools. It is used for the graphical analysis of an algorithm. It helps to represent the flow of the process from the input to output. A flowchart that represents the workflow of activities is known as an activity diagram.There are so many ways that can help people to understand computer technologies and their applications. One of them is a flowchart diagram.

Say you have a list value like this:
spam = ['apples', 'bananas', 'tofu', 'cats']
Write a function that takes a list value as an argument and returns
a string with all the items separated by a comma and a space, with and
inserted before the last item. For example, passing the previous spam list to
the function would return 'apples, bananas, tofu, and cats'. But your func-
tion should be able to work with any list value passed to it.
