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...
The first thing you have to do is create the templates folder and inside this folder, insert the example.html file. Note there are two variables in use in the template inside {{ }}. This is a special format to include Python code inside the template, allowing for dynamic conte...
