Trying to make a board with turtle, nothing happens when running script - Quascia - Oct-28-2023 Hello, I'm trying to make a board with turtle ( which I'm new to ) using loops and functions, but nothing seems to work. When I run the script, nothing happens. (I use Pyzo as an IDE) There are 2 functions : one for making the lines, and one for making the columns. There must be a loop that repeats for n times which determines the number of lines there will be. ; length is obviously the number of pixels the line will be. It's the same thing for columns . Also, between each lines / columns, there must be 20 pixels. Here is my code : import turtle def lines(n,length): for i in range(n): turtle.pen(fillcolor = "blue", pencolor = "black", pensize = 3) turtle.forward(length) turtle.up() turtle.right(90) turtle.forward(20) turtle.left(90) turtle.down() turtle.up() turtle.end_fill() turtle.done() window.exitonclick() lines(3,32) def columns(n,length): for i in range(n): turtle.pen(fillcolor = "green", pencolor = "black", pensize = 3) turtle.right(90) turtle.forward(length) turtle.up() turtle.left(90) turtle.forward(20) turtle.right(90) turtle.down() turtle.end_fill() turtle.done() window.exitonclick() columns(5,7)Can someone help a beginner ? Thanks ! RE: Trying to make a board with turtle, nothing happens when running script - DPaul - Oct-28-2023 Some possible improvements: - turtle up and down must be in the right sequence - end fill should be preceded by begin fill. - How many rows & columns are you drawing ? Paul RE: Trying to make a board with turtle, nothing happens when running script - Quascia - Nov-01-2023 (Oct-28-2023, 01:52 PM)DPaul Wrote: Some possible improvements:The number of rows and columns depends on what we put instead of " n ". So for example, if I put lines(5,87) there will be 5 lines of 87 pixels each. It's the same for columns. RE: Trying to make a board with turtle, nothing happens when running script - deanhystad - Nov-01-2023 This loop draws 1 line. for i in range(n): turtle.pen(fillcolor = "blue", pencolor = "black", pensize = 3) # Place in front of loop. turtle.forward(length) turtle.up() turtle.right(90) turtle.forward(20) turtle.left(90) turtle.down() turtle.up() # <- Pen is up when second iteration of loop runsI would start by changing the code to this: import turtle def lines(n, length): turtle.pen(fillcolor="blue", pencolor="black", pensize=3) turtle.begin_fill() for i in range(n): turtle.forward(length) turtle.up() turtle.right(90) turtle.forward(20) turtle.left(90) turtle.down() turtle.end_fill() def columns(n, length): turtle.pen(fillcolor="green", pencolor="black", pensize=3) turtle.begin_fill() for i in range(n): turtle.right(90) turtle.forward(length) turtle.up() turtle.left(90) turtle.forward(20) turtle.right(90) turtle.down() turtle.end_fill() lines(3, 32) columns(5, 7) turtle.done()Now you can at least see the turtle errors. |
