+# exercise 6.4 from unit 6
+'''
+You are subscribed to a Python website that sends you a challenge task to your email every week. You entered your inbox and noticed that you received
+ the following challenge from the website.
+
+The title of the letter: "Connect the dots".
+
+The content of the letter: "Will you be able to find out which animal it is?"
+
+You have to write a Python code that creates an image in which connected lines are drawn between all the points - that way you
+ can find out which animal it is. Use the code above as a skeleton for your program. Successfully!
+
+Guidelines:
+
+The Python code you received contains two lists: first and second. Each of them contains points that must be connected with a line.
+ The points are represented by a sequence of x and y coordinates as follows: [x, y, x, y,...] where each pair of adjacent members constitutes one point.
+Search the Internet for an external package that can help you solve the task (for example PIL). Download and install it on your computer
+(if it doesn't already exist).
+No particularly complex code is needed. The challenge can also be solved in a few single lines.
+
+First hint
+You must draw a continuous line connecting the points in each list (each point is represented by two members of x and y in the list).
+ When you are finished, save your drawing as an image in the project folder and open it - there the desired animal will appear to you
+ (another option: just present the picture when you finish drawing without saving it).
+
+Second hint
+To draw a continuous line between points you need to find an external Python package that has graphics capabilities and install it on your computer.
+ There are many solutions to the task, one of them is using the Image and ImageDraw modules from an external package called PIL.
