Using 'colors' instead of 'color' parameter

Using British spelling 'colour'

Using 'col' which is not a valid parameter

The correct parameter name to set bar colors in plt.bar is color.

Fill both blanks to create a bar chart with a title and y-axis label.

Matplotlib

import matplotlib.pyplot as plt

categories = ['Jan', 'Feb', 'Mar']

Fill all three blanks to create a bar chart with custom colors, x-axis label, and title.

Matplotlib

import matplotlib.pyplot as plt

categories = ['Red', 'Green', 'Blue']
values = [7, 3, 5]
colors = ['#FF0000', '#00FF00', '#0000FF']

plt.bar(categories, values, [1]=colors)
