Using python 3, how do you ensure that your program is case insensitive? Can someone please explain. Thank you in advance!

a) Write a program to quiz the user on a topic of your choosing. Here are the criteria: Your program "L3Q1 initials.py" must start with a commented ID Box AND include a comment that indicates the purpose of the program. Your program should: (a) Display a title reflective of your quiz topic (b) For each of your mandatory FOUR questions: a. Display the qucstion b. Prompt the user for an answer and allow them to type it in. Ensure your program is not case sensitive. c. Indicate whether the answer is correct or not. (See sample output) (c) Once all the questions have been answered, output the number of questions that the user answered correctly. The sample output provided shows you one example run based on the solar system (with four questions). Your output should be similar but reflect your own quiz topic and the user input answers.
