The implementations look quite similar! Generalize this logic by writing a function count_cond, which takes in a two-argument predicate function condition(n, i). count_cond returns a one-argument function that takes in n, which counts all the numbers from 1 to n that satisfy condition when called. def count_cond(condition): """Returns a function with one parameter N that counts all the numbers from 1 to N that satisfy the two-argument predicate function Condition, where the first argument for Condition is N and the second argument is the number from 1 to N.
