Coding Custom min() and max() Functions
00:00
With the min_max() helper function in place, you can define your custom versions of min() and max(). Go ahead and add the code seen on-screen to the min_max.py file.
00:14
First, you import gt() and lt() from the operator module. These functions are the functional equivalent of the > and < respectively. For example, the expression seen on-screen is equivalent to the function call seen on-screen.
00:30
You’ll use these functions to provide the operator argument to min_max(). Just like min() and max(), custom_min() and custom_max() take *args, key, and default as arguments and return the minimum and maximum values, respectively. To perform the computation, these functions call min_max() with the required arguments and with the appropriate comparison operator function. In custom_min(), you use lt() to find the smallest value in the input data. In

custom_max(), you use gt() to get the largest value. You’ve finished coding your own versions of min() and max() in Python.
01:31 Now go ahead and give them a try. You can see them in action on-screen.
02:55 In the next section of the course, you’ll take a look back at what you’ve learned.
