Write a function called user_input() that takes an integer n as a parameter. Thisfunction should display the integer n to the user and prompt them to enter its equivalentbinary value (the user just has to make a guess here). Your function should return theuser input.
Focus on string operations and methods You work for a small company that keeps the following information about its clients: • first name • last name • a 5-digit user code assigned by your company. The information is stored in a file clients.txt with the information for each client on one line (last name first), with commas between the parts. For example Jones, Sally,00345 Lin ,Nenya,00548 Fule,A,00000 Smythe , Mary Ann , 00012 Your job is to create a program assign usernames for a login system. First: write a function named get_parts(string) that will that will receive as its arguments a string with the client data for one client, for example “Lin ,Nenya,00548”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and newlines from the end of the parts. You’ll need to use some of the string methods that we covered in this lesson You can test your function by with a main() that is just the function call with the…

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
