Module to Calculate Statistics

You are working for a prestigious data science company. You receive raw numerical data every day, and your manager wants to analyze this data more closely. They are particularly interested in the mean, median, and mode of each data set.

As the company grows, the manager wants to automate this process, so they have asked you to create a Python module named stats.py that includes functions to calculate these statistical parameters. That file should include 3 functions mean(), median(), and mode() that should get a list of floating-point numbers as an argument and return a number. In case there are multiple modes with same frequency you should return the smallest one.

The input and output are handled automatically by the main.py module.
