Question

This is an example given on pages 97-98 of Python Programming, 2nd edition by John Zelle. I am attempting to make a bar chart that shows the growth over 10 years of an investment. For some reason I am getting a syntax error when I use "Text" the second time when attempting to create the labels on the left edge of the graph. I am not sure what is going on here. Even the solution given for excersise 6 (a more intensive version of the problem above) has the same exact code for creating the labels. Please help, thank you.

Explanation / Answer

There is a syntax error:

Text(Point(20, 230), '0.0K').draw(win)

Text(Point(20, 180), '2.5K').draw(win)

Text(Point(20, 130), '2.5K').draw(win)

Text(Point(20, 80), '2.5K').draw(win)

Text(Point(20, 30), '2.5K').draw(win)

check once, if you still getting error, please give me comment...
