This exercise is part of the course

Statistical Thinking in Python (Part 1)

Compute the mean petal length of Iris versicolor from Anderson's classic data set. The variable versicolor_petal_length is provided in your namespace. Assign the mean to mean_length_vers.
Hit submit to print the result.

Have a go at this exercise by completing this sample code.

# Compute the mean: mean_length_vers


# Print the result with some nice formatting
print('I. versicolor:', mean_length_vers, 'cm')
