Jul 22, 2016 · You could use pd.crosstab to create a frequency table -- i.e. to count the number of is_overdue s for each org. 'id': [1, 2, 3, 4, 5], . 'is_overdue': [True, False, True, True, False], 'org': ['A81001', 'A81002', 'A81001', 'A81002', 'A81003'] yields. I really like this answer - I've never seen crosstab before.

Booleans represent one of two values: True or False. In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. When you compare two values, the expression is evaluated and Python returns the Boolean answer:

Jan 21, 2011 · Here's a really simple question regarding pythonic coding. Given a list, if you want to calculate the proportion of items satisfying (A and B), out of those satisfying (A), a natural solution would be: Imagine the list is of integers, condition A is (>3), condition B is (>5) if item > 3: count += 1. if item > 5: correct += 1.
