In a file named benfordturtle.py, you will write a Python program that will read in a filename from the user. The file will contain one number on each line. Your program will compute the frequency (as a percentage of the whole) of the first digit of each number. Then it will use the turtle module to draw a horizontal bar chart. Important note: the Turtle Bar Chart. The main page shows a vertical bar chart rather than the required horizontal one. Also note, you are not required to define your own functions.

In terms of bar chart style, you may use bars like those shown in the Turtle Bar Chart link, or use a bar that is drawn using a single thick line. See examples below. Note: The colors are up to you.

Whichever bar style you choose, you must show the digit, and the frequency as text on the right-hand side of the bar.

One of the tricky things about drawing the bars is getting the length correct. However, the turtle module has you covered. The screen has a method named setworldcoordinates that allows you to change the coordinate system being used. You are required to use setworldcoordinates to have the origin, (0,0), be set to the upper-left of the screen with a maximum x value of 100 (for 100%). The height is left to you.

Your program must be able to handle any file in the same format, including files not given here.
