The text you provided is a Python script that generates a pie chart using the matplotlib library. Here's a step-by-step explanation:

1. The first four lines define the data and settings for the pie chart. The 'labels' list contains the labels for each section of the pie chart. The 'sizes' list contains the sizes of each section. The 'colors' list contains the colors for each section.

2. plt.figure(figsize=(6, 6)) sets the size of the figure to 6x6 inches.

3. plt.pie(sizes, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=140) creates the pie chart with the specified sizes, labels, colors, percentage format, shadow, and start angle.

4. plt.title('Pie Chart') sets the title of the chart to 'Pie Chart'.

5. plt.axis('equal') ensures that the pie chart is drawn as a circle, not an ellipse.

6. plt.show() displays the pie chart.
