List Processing

In this exercise we process data stored in a List, which is an important concept in many programming languages.

In a file named list_processing.py, write a function named listproc that:

• Takes two arguments, a list of String and a boolean flag.
• Returns a String that is the concatenation of the list values.
• If the flag is set to True, transform each list element which has an even index value to an uppercase String.

Calling listproc(['one','two','three'], True) returns ONEtwoTHREE, for example.

Mentoring topics

Discuss the use of lists, sets, and others similar structures.
