What would cause an algorithm to have O(log n) complexity?
...er dividing n in half i times we'll have a value that is at most 1. The smallest i for which this is guaranteed is roughly log2 n, so if we have an algorithm that divides by 2 until the number gets sufficiently small, then we can say that it terminates in O(log n) steps.
An important detail is tha...

Unicode (UTF-8) reading and writing to files in Python
...le you have "\xc3" in it. Those are 4 bytes and in your code you read them all. You can see this when you display them:
