Python turtle custom canvas background color

Turtle is a simple and easy-to-use drawing package for python, which can control the drawing in real time by designing coordinates.

The installation is simple, one line of command:

Pip install turtle

Here is only how to set the background color of the canvas. It is generally set at the beginning of the drawing, you can use the screensize (width, height, bg) function, in which the three parameters are the width, height and background color of the canvas. The unit of width and height is pixels, and if expressed in decimals, the size is determined as a percentage of the width and height of the screen. However, if you only set the canvas size, it is not possible to control the window size, which needs to be set using the setup (width, height, X, Y) function. The first two parameters are still width and height, the rear X and Y are set window coordinates, the default is the center of the window as the coordinate origin, the X axis is horizontal to the right, and the Y axis is vertically upward. The difference between the window and the canvas is that the window can control the size of the display window, while the canvas is the size of the drawing area within the window. If the canvas size is larger than the window, a scroll bar will appear on the window. Background colors can be expressed in two ways, one is a common color, which can be described directly in English, such as "black", "white", "yellow", "pink", "blue", "red" and so on. For example, I want a window that is 0.5 times the width and height of the screen, with a green background:

Import turtle as t # Import turtle package t.setup (0.5,0.5) # set window size t.screensize (bg= "green") # set background color t.done () # finished drawing (this line must be added so that it won't get stuck)

But what if I want to set the unusual color as the canvas background? This involves the second expression of color-hexadecimal. The hexadecimal RGB color comparison table can be viewed here. For example, here I want a Christmas green canvas 500 pixels wide and 600 pixels high. The code and effect are as follows:

Import turtle as t # Import turtle package t.setup (500,600) # set window size t.screensize (bg= "# 006400") # set canvas size and background color t.done () # finished painting (this line must be added so that it won't get stuck)
