Question

Assignment Requirements

Write a python application that consists of two .py files. One file is a module that contains functions used by the main program. NOTE: Please name your module file: asgn4_module.py

The first function that is defined in the module is named is_field_blank and it receives a string and checks to see whether or not it is blank. If so, it returns True, if not it return false.

The second function that is defined in the module is named is_field_a_number and it receives a string and checks to see whether or not it is a number. If so, it returns True, if not it return false.

The other .py file should properly call a main function that does the following...

1. Prompts the user to enter their first name.

Call the is_field_blank function to see if nothing was entered.
If nothing was entered it displays the following message...

"First Name must be Entered"

...and re-prompts the user to enter the first name. It does this repeatedly until the user enters a first name.

2. Prompts the user to enter their last name.

Call the is_field_blank function to see if nothing was entered.
If nothing was entered it displays the following message...

"Last Name must be Entered"

...and re-prompts the user to enter the last name. It does this repeatedly until the user enters a last name.

3. Prompts the user to enter their age.

Call the is_field_blank function to see if nothing was entered. If nothing was entered it displays the following message...

"Age must be Entered"

...and re-prompts the user to enter their age. It does this repeatedly until the user enters a age.

Once the user has entered a non-blank age call the is_field_a_number function to see if the age entered is a number. If not, display the following message...

"Age must be a Number"

...and re-prompt the user to enter their age. It does this repeatedly until the user enters a numeric age.

4. If the user's age is over 40 display a message in the following format:

Well, (first name) (last name) it looks like you are over the hill

Otherwise display a message in the following format:

It looks like you have many programming years ahead of you (first name) (last name)

5. Follow the format of the "Sample Program" below with the first and last lines appearing as shown. Also, be sure to use line skipping and spacing the way I show below.

Module Documentation Requirement

You MUST add Python Module Documentation to the the module .py program file

Running a Sample Program

Below is a example of how your program might run if you used the same answers to the prompts I used below. Your program should run in a similar manner... no matter what names (data) are entered.

NOTE: The data I entered appear in maroon bold

Sample Run...

Answer 1

Please find below the code, code screenshots and output screenshots. Please refer to the screenshot of the code to understand the indentation of the code.  Please get back to me if you need any change in code. Else please upvote

CODE:

import asgn4_module

print("Assignment 4\n")

fname = "" #Initialize firstname as empty string

while asgn4_module.is_field_blank(fname): #loop untill a non-empty first name is entered

    fname = input("What is your first name? ") #Reading the first name

    if asgn4_module.is_field_blank(fname): #display error if first name is an empty string

        print("First Name must be Entered")

lname = "" #Initialize lastname as empty string

while asgn4_module.is_field_blank(lname): #loop untill a non-empty last name is entered

    lname = input("What is your last name? ") #Reading the last name

    if asgn4_module.is_field_blank(lname): #display error if last name is an empty string

        print("Last Name must be Entered")   

age = "" #Initialize age as empty string

#loop untill a non-empty age as number is entered

while asgn4_module.is_field_blank(age) or not asgn4_module.is_field_a_number(age):

    age = input("What is your age? ") #Reading the age

    if asgn4_module.is_field_blank(age): #display error if age entered is empty

        print("Age must be Entered")

    else:

        if not asgn4_module.is_field_a_number(age): #display error if age is not a number

            print("Age must be a Number")

#If the user's age is over 40 display a message in the following format:

#Well, (first name) (last name) it looks like you are over the hill

if int(age) > 40:

    print("Well," ,fname, lname, "it looks like you are over the hill")

#Otherwise display a message in the following format:

#It looks like you have many programming years ahead of you (first name) (last name)

else:

    print("It looks like you have many programming years ahead of you", fname, lname)

print("END OF ASSIGNMENT 4")

CODE (asgn4_module.py)

#Function to chech wheteher the string is empty or not

def is_field_blank(string):

    if string == "":

        return True #return true if string is empty

    else:

        return False #else return false

#Function to check whether the string is a number or not

def is_field_a_number(string):

    if string.isdigit():

        return True #return True if string is a number

    else:

        return False #else return false
