main()

This program reads points from a text file and creates a String Art cardioid pattern by drawing a series of lines between the points. For this question, you may use any colours of your choosing b) Complete the get list of_tuples from_file(filename) function Complete the get_list of_tuples_from file) function which is passed the name of a file as a parameter. Each line of the file contains two floating point numbers separated by spaces. The function reads the information from the file and returns a list of tuples. Each tuple in this list of tuples is made up of the two numbers taken from each line of the input file and rounded to the nearest whole number. The function returns the list of tuples c) Complete the draw_ outer_circle(a_canvas, centre x, centre_y, radius) function. Complete the draw outer circle(function. This function is passed four parameters: the Canvas object and three integers (the centre x position, the centre y position and radius of a circle). The function draws the circle in the given position and of the given radius (distance from the centre of the circle to the edge of the circle) d) Complete the draw_cardioid connections(a_canvas, points_ on_circumference) function. Complete the draw cardioid connections() function which is passed two parameters: the Canvas object and a list of tuples each made up of two integers representing a point on the circumference of a circle (circle outline). The function draws ALL the lines connecting the points in the list of tuples in the way described below. Please read the two Important Notes lower down on this page point number 1 connects to point number 2, point number 2 connects to point number 4
