Use Python to solve the following question
Write a program that simulates an authentication portal, the program should contain two functions: A) Signup function: it accepts an email and a password from the user, you should check the user's inputs by using RE (Regular Expression). - The email input should be a valid email. - The password must contain at least one special character, digit, and starts with an upper case letter. If the pattern matches against the password and email, then show a welcome message and save the user credentials to a file called "credenials.txt", every single email and password in a new line, and separate them with a comma (). B) Login function: ask the user to input his/her email and the password. you have to check the input data, if it is true show the user a welcome message, if not, let him/her try again. The user is allowed to try login in only three times, and after that shows a message that the service is blocked temporarily. You have to ask the user to choose the flow by entering (1) for signup and (2) for login.
