Part I Instructions:

# This is the flower box and it should be at the beginning of each assignment
# You must add comments to your code
# Program name     : Wk2P1_firstname_lastname.py
# Student Name     : Ymmas Azaba
# Course                : ENTD220
# Instructor           : My Instructor
# Date                   : Any Day# Copy Wrong        : This is my work

You are going to create the following:

A simple calculator to accept two numbers and print the addition, subtraction, multiplication and division of the two numbers.

You are required to store each input number in a separate variable.

      1) You should also store each calculation in a variable
      2) You will get an error if you divide by zero, you will address this problem next assignment

Sample output

This is my first programming assignment
Enter your First number  —> 25
Enter your Second number —> 14

The Result of 25+14=39.0
The Result of 25-14=11.0
The Result of 25*14=350.0
The Result of 25/14=1.78571428571

Submission Instructions:

Make sure that you save your code in a text file in this format. Check your file after the upload to see if they are readable. You can paste your code in the student submission text area.


Part II Instructions:

# This is the flower box and it should at the beginning of each assignment
# You must add comments to your code
# Program name   : Wk2P2_firstname_lastname.py
# Student Name   : Ymmas Azaba
# Course              : ENTD220
# Instructor         : My Instructor
# Date                 : Any Day

 You are going to enhance the prior assignment by doing the following:

1) Limit the input range from -100 to 100 for each input number
2) Prevent dividing by zero (Do not use try-except)

3) Instead of hard coding values from -100 to 100, let the user enter the range


See sample output for messages.
Sample output

Enter your Lower range   —> -100
Enter your Higher range  —> 100
Enter your First number  —> 50
Enter your Second number —> 20

The Result of 50+20=70.0
The Result of 50-20=30.0
The Result of 50*20=1000.0
The Result of 50/20=2.5

Thanks for using our calculator!

Enter your Lower range   —> -50
Enter your Higher range  —> 50
Enter your First number  —> 20
Enter your Second number —> 0

The Result of 20.0+0.0=20.0
The Result of 20.0-0.0=20.0
The Result of 20.0*0.0=0.0
The Result of 20.0/0.0=You cannot divide by Zero

Thanks for using our calculator!


Enter your Lower range   —> 10
Enter your Higher range  —> 50
Enter your First number  —> 5
Enter your Second number —> 60

The input values are out side the input ranges
Please check the numbers and try again
