Python Python Basics (2015) Python Data Types List Creation

List issues for challenge

Ok, the earlier challenges, I got through them with no problems, now, I watch the videos and I'm not passing the videos. I read through the teachers notes and still no clues as to what I'm missing. So, the task is to make a list of five colors with a list name of colors. The error that comes back is that blue is not defined and so on (as you remove colors). So, I tried putting str in front of the brackets, nope didn't do the trick. The I tried placing quotations at the beginning and end of the colors list, within the brackets; this was a no go as well. In the video he strictly deals with integers in his lists. So, since now they are asking us to create a list with five colors are we supposed to type it differently?

lists.py
Colors=[blue, black, red, orange, yellow]

Your colors are actually color names (strings) and so each one should be enclosed in quotes.

Also, the instructions said to make a variable named "colors" (with a lower-case "c"), but you wrote "Colors" (with a capital "C"). Since Python is case-sensitive, these identifiers reference two different things.

You have put quotations surrounding each value. Also, you have to name your list colors instead of Colors. Hope this helps!

Oh my goodness, I didn't even notice that I had done that, thank you, both of you! Gosh I suck at this.
