Python Pygame Syntax errors, that have never before happened

I am getting a syntax error, I have searched for many hours on why this is happening but I cannot seem to find a reason. I am getting sytax errors on:

# -- Pictures ---
image[5] = (r"E5")

and on

# --- Colours ---
black = (0,0,0)

Any help is appreciated as I have never had this problem before with those specific pieces of code
