Question

Write a Python program to create userids:

You work for a small company that keeps the following information about its clients: • first name • last name • a 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. In the clients.txt file is: Jones, Sally,00345 Lin,Nenya,00548 Fule,A,00000

Your job is to create a program assign usernames for a login system. First: write a function get_parts(string) that will that will receive as its arguments a string with the client data , for example “Lin,Nenya,00358”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and end of the parts. You’ll need to use split(), lstrip() and rstrip() You can test your function by with a main() that is just the function call with the argument typed in. Second: write a function make_user(param) that will receive as its arguments three strings - the first name, last name, and client number and return the username. The user name should be created as • The first two characters of the first name, in lower case • The first two characters of the last name, in lower case • The last three characters of the user number For the example, the username for user Nenya Lin will be neli348 You’ll need to use slices, lower() and concatenation. You can test your function by with a main() that is just the function call with the arguments typed in. Finally: After your functions are working, write a main program to open the file (provided in the Assignments section on Blackboard), create usernames for the clients and print out client names and user names in a neat report format. For example

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

Note: Please maintain proper code spacing (indentation), just copy the code part and paste it in your compiler/IDE directly, no modifications required.

#code

''' method to convert a line of data to individual parts'''
def get_parts(string):
    #splitting fields by comma
    fields=string.split(',')
    #taking value at index 0 as last name, stripping trailing and leading spaces
    last=fields[0].lstrip(' ').rstrip(' ')
    # taking value at index 1 as first name
    first=fields[1].lstrip(' ').rstrip(' ')
    # taking value at index 2 as user code
    usercode=fields[2].lstrip(' ').rstrip(' ')
    #returning all three values
    return first,last,usercode

''' method to create user id from first, last names and usercode'''
def make_user(first, last, usercode):
    #combining first two characters from first name, first two characters from last name
    #and last three characters from usercode, and returning it
    return first.lower()[:2]+last.lower()[:2]+usercode[-3:]

def main():
    #opening 'clients.txt' file, make sure file exists in same directory and is valid
    file=open('clients.txt')
    #printing heading
    print('{:15s} {:10s}'.format('Client','Username'))
    #printing a line of '====' characters
    print(25*'=')
    #looping through each line in file
    for line in file:
        #removing trailing newline if exists
        line=line.strip()
        #splitting into individual parts
        first,last,usercode=get_parts(line)
        #finding userid
        userid=make_user(first,last,usercode)
        #displaying values
        print('{:15s} {:10s}'.format(first+' '+last,userid))
    #closing file once loop is over
    file.close()

#calling main()
main()
