Python Pie Chart

This builds on the earlier Python Bar Chart. Differences are highlighted below.

Data

• Same as Python Bar Chart.

Script

• Generate a list of Seasons from the data.
• Generate a list of Players from the data. Iterate through data, adding player names to a list. After that, convert the list to a dictionary, which automatically removes all duplicates, then convert back to a list, and sort.
• Request the user to enter a choice from list of Seasons.
  • Utilize a Try-catch to ensure only numerical data is entered.
  • If value is numerical but out of bounds, do-over.
  • If value is 0, end program.
• Request the user to enter 1 for Goals and 2 for Appearances.
  • Utilize a Try-catch to ensure only numerical data is entered.
  • If value is numerical but out of bounds, do-over.
  • If value is 0, end program.
• Use the selected season and stat to generate the Pie Chart.

Chart

We use the matplotlib library to plot the pie chart.

• colors is an argument passed into the pie() method. It is a list that contains Hex values. The pie wedges will be colored accordingly.
• explode is an argument passed into the pie() method. It is a list that contains float values between 0 and 1. The pie wedges will be displaced from the center according to the value.
