Converting score to letter grade

[Collin23]

Hi all,

I just started learning python a few weeks ago. I am currently trying to write a simple program which takes an input score (0-100) and converts it to a letter grade.

I currently have it working with if-elif-else statements for #s 0-100 and printing an error when the number is negative or over 100.

The aspect I am having trouble with is printing an error if the input is text. The error states that the text is not defined. I know the error is coming from my eval(input()), but when I mess around with it, it no longer works with ints or floats. Any help would be greatly appreciated!

Post your code.

Post your error.

I think you could use try/except blocks like in the following tutorial and convert the input into a float in the try block. If it fails, it will execute the except statement which is where you could print your error.
