PYTHON BASICS
Defaults and keywords
You can give parameters default values. If the caller leaves them out, Python uses the default. You can also pass arguments by keyword (by name) instead of position.
How it reads
color="neon" sets a default value for color
glow(brightness=10) specifies brightness by name, while color defaults to "neon"
str(brightness) converts the integer to text so we can add it to other text
Cloud tip: All parameters with default values must come after parameters without default values.
