P3_elif.py 10 points
The Python if, elif, elif, else statements allow assigning a data item to one and only category. elif means "else if".
Example
After getting a value such as "very short" to category, Python jumps past all remaining elif and else; it then prints height and category.
For this part of the assignment, use if elif elif else …
You will ask for a name, or "Quit" then for the number of points earned on a test. Using this table below, assign a letter grade, print the name, points and grade, then repeat.

1 point
Turn the turtle right nudge degrees
Move forward bump units
Change size to be 4 units larger
Your drawing will look like this — you might have some different color choices, or number of colors, and your spiral might curve to the left, or to the right, but it should show some filled squares looking more or less similar to this:
