python only

Write a program which asks the user to enter their first name and their family name. The program should then create a UPI by concatenating the first letter of the first name, the first 3 letters of the family name and a random number between 100 and 999 (inclusive). If the family name has less than 3 letters, then the UPI is created by concatenating the first letter of the first name, then all the letters of the family name and a random number between 100 and 999 (inclusive). Notes: - Assume all letters will be in lower case. - You do not need to import the random module as it has already been done for you. - You can use the built-in function str() to convert the number to a string before concatenating it into the UPI. - The output must be in the format shown in the example below, including the format of the prompt, and all spaces and punctuation
