# One of several ways to do a ternary operation in Python
# For more discussion, see: http://drj11.wordpress.com/2007/05/25/iversons-convention-or-what-is-the-value-of-x-y/

# "AB"[True]  => A, likewise "AB"[False] => B
# In this way you can index any two item list with a test:

card_type = ["Low", "High"]][card_value < 10]
