my assignment is to design a structure that will interrogate a string of characters to see if the email is valid or invalid.In Python, there are multiple ways to complete almost any task. Performing a simple Google search will reveal many interesting and elegant solutions using a variety of techniques. In this lesson we are working with string manipulation.Thus, the solution must be obtained using string manipulation. (this is a special note from my instructor.)
