Lestion 1 (4 points): Purpose: To practice slicing and using string methods Degree of Difficulty: Easy An email address is a sequence of characters with the following structure: - it contains exactly one @ character - there are 1 or more characters before the @. We call these characters the username - There is at least one period (.) SOMEWHERE after the @ - IMMEDIATELY after the @ there are one or more characters that are NOT periods. We call all the characters in between the @ and the first-period-after-the-@ the domain - The last section after the last period is called the Top Level Domain or TLD For this question, you will write a program that lets the user type in a valid email address, and reports the username and TLD components of that address. Your program may assume that the user always types a correctly-formatted email address. Hint: Tools such as slicing and the string method .find() or .rfind() will probably be the most useful here. Sample Runs Here is one possible sample run. Green text was entered by the user, and the blue text is based on that input. Enter email address: ash@pokemon.kanto.jp Username : ash TLD : jp Here is another one. Enter email address: gang.li@usask.ca Username : gang.li TLD : ca
