Exercise 1 (What is your grade?)  

Step 1

Python allows you to solicit information from the user.
One way to do this is using the input() function. Here is an example of how to use it.

user_input = input('Give me a number?')
print('You entered', user_input)

Run this code and explore.

Task

Write a Python program that takes a numerical grade (0-100) as input and outputs the corresponding letter grade based on the following criteria:

Grade	Score Range
A	70 - 100
B	50 - 69
C	35 - 49
Fail	0 - 34

Note:

• Here is an example of the type of exchange expected.

  Enter the student's score: 85
  The student's letter grade is: A

• Ensure your program handles unexpected inputs gracefully and displays a relevant error message.
