This function can be used to find the time taken for a piece of code to execute. All we have to do is, just run the function before and after the execution of the code, and then find the difference between them.Example 2: Find the time taken for a code to execute....
In the first comparison, we are looking for a Boolean True or False. In the second comparison, we are looking for the time delta showing us the time difference between the two objects. Before we begin, we need a couple of datetime objects to work with: from datettime import datetime dat...

A timedelta object represents a duration, the difference between two dates or times. A timedelta object can be instantiated as follows: datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0) All arguments are optional, with a default value of 0....
In this chapter we cover two libraries that will make an enormous difference in how you deal with temporal matters. arrow is a reimagined library for working with datetime objects in which timezones are always present, which helps to minimize a large class of errors that new Python programmers...
Output: >>> WTF() is WTF() I I D D False >>> id(WTF()) == id(WTF()) I D I D True As you may observe, the order in which the objects are destroyed is what made all the difference here.▶ Disorder within order *from collections import OrderedDict dictionary = dict() dictio...
