How to use Python to draw a Christmas tree, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

T.pensize (10) # modify brush size

Effect picture:

①, this is the effect of t.pensize (10).

②, this is the effect of t.pensize (5).

Full version of the code:

Import turtle ast # as is an alias. The subsequent calls are all turtlefrom turtle import * import random as rimport time n = 100.0t.pensize (10) # modify the brush size speed ("fastest") # define screensize (bg='black') # define the background color, you can change your own color left (90) forward (3 * n) color ("orange", "yellow") # define the color of the top star, and the outer circle is orange Inside is yellowbegin_fill () left (126) for i in range (5): # draw pentagram forward (n / 5) right (144C) # Angle of pentagram forward (n / 5) left (72) # continue to change angle end_fill () right (126) def drawlight (): # define the method of drawing colored lights if r.randint (0,30) = 0: # if you think there are too many colored lights We can enlarge the range of values.
