You can use that function to do a binary search in Python in the following way: Python import math def find_index(elements, value): left, right = 0, len(elements) - 1 while left <= right: middle = (left + right) // 2 if math.isclose(elements[middle], value): return middle if...
(x, y, z) = Tuple # ValueError: too many values to unpack (expected 2) (x, y, z, i) = Tuple # ValueError: not enough values to unpack (expected 4, got 3) 8. Named tuples Python provides a special type of function called namedtuple() that comes from the collection module. Name...
