Kumite (ko͞omiˌtā) is the practice of taking techniques learned from Kata and applying them through the act of freestyle sparring.
You can create a new kumite by providing some initial code and optionally some test cases. From there other warriors can spar with you, by enhancing, refactoring and translating your code. There is no limit to how many warriors you can spar with.
A great use for kumite is to begin an idea for a kata as one. You can collaborate with other code warriors until you have it right, then you can convert it to a kata.

We have a programmer who is at peak performance when (1) they have coffee, (2) it's a weekend, (3) the hour is before 7:00 or after 22:00, and (4) the number of lines of code they produce is between 40 and 76, inclusive. Return True if the programmer is at peak perfomance, or False otherwise.
def coffee_and_code(coffee, weekend, hour, code): return True if coffee and weekend and (hour <= 7 or hour >= 22) and code in range(40, 77) else False- def coffee_and_code(coffee, weekend, hour, code):
pass- return True if coffee and weekend and (hour <= 7 or hour >= 22) and code in range(40, 77) else False
why map when you can listcomp?
