I am trying to make a drawing board in pygame but I want to be able to change the opacity using RGBA but it doesn't seem to be working, my code below:

z = 0
i9 = 1
circle = []
long = 0
drawing_name = ''
load_name = ''
th = False
fill = r,g,b,a
WHITE = 255,255,255
file = 0

Can you help me?

If you work for a larger organization, the chances are that you may sooner or later find yourself reporting to someone with a very different background and, as a result, perspective on an organization, roles, etc.; for example, someone with a developer background reports to a marketer. Trying to explain a career and how it has led you to a place and how you might wish it to progress is difficult if the person you’re talking with has little exposure or understanding. Or, it could be simply that the person you’re talking to is a visual thinker.

This is where I found myself recently. So, to facilitate a conversation, I thought I'd try to describe my career and desired direction more visually. After all, CV-style bio/representations are rather abstract, focus on a timeline, and need a domain understanding to appreciate the value.
