Let's convert a number grade to a letter grade, using if and elif statements and comparisons.

• input, print
• type conversion (str to int)
• comparisons (< <= > >=)
• if, elif, else

1. Have the user enter a number representing the grade (0-100)
2. Convert the number grade to a letter grade

• 90-100: A
• 80-89: B
• 70-79: C
• 60-69: D
• 0-59: F

Find the specific letter grade (A+, B-, etc). You can check for more specific ranges using if statements, or use modulus % to get the ones-digit to set another string to '+', '-', or ' '. Then you can concatenate that string with your grade string.
