put early in your code (e.g. main.py)

import sys
from IPython.core import ultratb

# the StackOverflow example showed this, but these values were defaults when I inspected.
# sys.excepthook = ultratb.FormattedTB(color_scheme='Linux', call_pdb=False)

# This works for me.
sys.excepthook = ultratb.FormattedTB()

# Verbose output
# sys.excepthook = ultratb.VerboseTB()

color_scheme

• NoColor: allows all of this module to be used in any terminal (the color escapes are just dummy blank strings).
• Linux: is meant to look good in a terminal like the Linux console (black or very dark background).
• LightBG: similar to Linux but swaps dark/light colors to be more readable in light background terminals.
• Neutral: a neutral color scheme that should be readable on both light and dark background
