if le > 2:

First, let's take a look at calculating averages.

IPO model.

Input: The number of calculated averages to be entered.

Processing: Average algorithm.

Output: Average.

After understanding the IPO mode of the program, we open the local Python IDE tool and create a new Python file named it.

Hello subject,** and the test screenshot is as follows:

I hope it can help the subject, welcome to ask.

In Python, the following rubber-bearing method can be used to calculate the average of a set of numbers:

Use the built-in functions sum() and len() to combine:

Use the numpy library:

Both methods can be used to quickly average a set of numbers. The first method makes macros work with Python's built-in functions, which can be applied to any iterative object, while the second method requires the installation of the numpy library, which is suitable for more complex numerical calculations.
