Python Crash Course exercise 15_10

has anyone done this? im talking about plotting the randomwalk using pygal. I try using pygals XY_chart, but it seems to want the coordinates like this : values = [(x1,y1), (x2,y2) ....] . I have two seperate lists of 5000 x-values and y-values. and want to format them together like this using a loop, but dont get how to do it.. Appreciate the help, cheers!
