Python, in all of its greatness, is often dismissed when needing to write performant and distributed applications. It’s considered to be slow and not suited for the task. In this course, you will find that with the right implementation of Python, you can write applications that scale horizontally, perform well, and are distributed. 

To kick things off, you’ll learn about CPU scaling, concurrency, and event loops, all of which are crucial for implementing a distributed system. After that, you’ll move on to queue-based distribution, lock management, and group memberships, which are fundamental concepts for maintaining availability and consistency in distributed applications.

In the last half, you’ll learn how to build a REST API, how to deploy your app to a PaaS, and how to optimize your application's performance.

By the end of this course, you’ll be more productive with Python, you’ll be able to write faster applications that are distributed, and you’ll have a great new skill that is highly coveted.

The Hacker's Guide to Scaling Python

## Problem

You are going to crack a 2 digit pin code in the following exercise. This pin code is used to open the locker of a bank.

However, there is a security system deployed at the bank locker that pin cannot be entered twice within **one** second. So, if anyone wants to crack it, they would have to wait one second after every wrong attempt.

Your task is to crack the pin code using the library `tenacity`. The skeleton code is provided, and the `crackPassword()` function is also implemented, which generates a random 2 digit number and check if this is the pin.

The hacker knows that they can try every combination from 11 to 99. However, they believe that they can crack it faster by trying randomly.

Please use the coding playground to complete the task provided below.

> To run the code below, press the Run button and run the command `python tenacity-test.py`.
