Qustion number 2 please, in paython language. 

Lab Exercises: Write a script that will generate a random number between 1 and 20 and the user needs to guess that number. If the user enters a wrong number, print a message that indicates that. The user needs to keep trying until the user guesses the right number. Once the user guesses the right number, the program needs to stop and print a message telling the user that he/she guessed the number. 1. 2. Write a function that will take an email from the user as an input, check if the email is in correct format: 2.1. Email Id (Text before the @ sign) with a length greater than 2. 2.2. @ sign 2.3. Valid domain (list of valid domains are: psut.edu.jo, hotmail.com, gmail.com) should be no spaces in the email at all. 2.5. The length of the email should not be greater than 20 characters. If any of the previous parts are missing, the script must notify the user with exactly which part is wrong. If all the parts are correct then the script must notify the user that it's a valid email address. 3. Using the file "passwd.txt" create a script that will create a new file that contains (per line): 3.1. "The user USERNAME id is USERID and their default shell is DEFAULT_SHELL" You need to replace USERNAME with the username, USERID with the user's ID and DEFAULT_SHELL with the user's default shell. Example: The user hamzah id is 1001 and their default shell is /bin/sh
