This article tells you about the simple code of python's cool special effects and the nice pattern code of python. I hope it will be helpful to you. Don't forget to bookmark this site.
1. How to use Python to make a fun and cool GIF dynamic map
import sys
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
fig, ax = plt.subplots()
fig.set_tight_layout(True)
# Ask about the size and DPI (dots per inch) of the graphic on the screen
# Note that when saving the graphics as a file, you need to provide a separate DPI for this
print('fig size: {0} DPI, size in inches {1}'.format(
fig.get_dpi(), fig.get_size_inches()))
# Draw a scatterplot that stays the same (will not be redrawn) and the initial line
x = np.arange(0, 20, 0.1)
ax.scatter(x, x + np.random.normal(0, 3.0, len(x)))
line, = (x, x - 5, 'r-', linewidth=2)
def 携腊update(i):
label = 'timestep {0}'.format(i)
print(label)
# update the line and axes (with a new x-axis label)
# Return the objects that need to be redrawn in this frame as a tuple
line.set_ydata(x - 5 + i)
ax.set_xlabel(label)
return line, ax
if __name__ == '__main__':
# will call the Update function for each frame
# Here FunAnimation sets a 10-frame animation with an interval of 200ms between each frame
anim = FuncAnimation(fig, update, frames=np.arange(0, 10), interval=200)
if len() > 1 and [1] == pure implicit 'save':
('', dpi=80, writer='imagemagick')
else:
# () will keep looping the animation
()
The following graph can be generated
2. Python language, use recursion to draw colored fourth-order pentagonal Koch snowflakes, and upload the code and Koch snowflake renderings?
import random
import turtle
def random_color():
rgbl=[255,0,0]
random.shuffle(rgbl)
return tuple(rgbl)
def koch(size,n):
if n==0:
(size)
else:
for angle in [0,60,-120,60]:
cc = random_color()
turtle.pencolor(cc[0], cc[1], cc[2])
(angle)
Lian Zhi Li builds a hole koch(size/3,n-1)
def main():
turtle.colormode(255)
turtle.setup(600,600)
turtle.penup()
(-200,100)
turtle. pendown()
turtle.pensize(2)
level=4 #4th order Koch snowflake, order
koch(400,level)
turtle.right(120)
koch(400,level)
turtle.right(120)
koch(400,level)
turtle.hideturtle()
()
main()
The effect is as shown in the search diagram:
3. Rock-paper-scissors python programming code
-
player = int(input("Please punch stone (1)/scissors (2)/cloth (3)"))
-
computer = 1
-
if((player == 1 and computer == 2) or
-
(player == 2 and computer == 3) or
-
(player == 3 and computer == 1)):
-
print("Oye! The waiter and the computer are so weak!")
-
elif player == computer:
-
print("There is a consonance in the heartbeat, let's have another game!")
-
else:
-
print("No, I want to fight with you until dawn!")
When executing, the first line must be copied separately, because you need to enter a value
4, python color python code
There is a drawing library called turtle in Python, let's introduce it first. importturtle (python uses import or from...import to import corresponding modules, which is similar to the include header file in C, please refer to the specific usage of rubber clap import) and turtle is a drawing library. Here I will only introduce a few commonly used ones. Function
turtle.setup (a, b, c, d) a, b two parameters control the width and height of the canvas, c, d properties control the position of the canvas; turtle.screesize (a, b, c) a, b control The width and height of the canvas, C controls the color of the canvas; for example: turtle.setup(800,400,200,200)//Create a canvas with a width of 800 pixels and a height of 400 pixels, and the coordinates are (200,200) Liang Sixian turtle.screensize(800,400,' green')//Create a hail pie canvas with a width of 800 pixels, a height of 400 pixels, and a color of green
5. Python code for drawing love
I've tried my best, but it might be a bit difficult to make a really good looking heart (except for the textures, but that's not good after all, right).
The following is the Python code:
from turtle import *
speed(0)#speed, if you think it is too fast, you can adjust it to 1 (1 is slow, 10 is fast, 0 is the fastest)
tracer(2)#Display the speed, if you think it is too fast, you can adjust it to 1 (same as above)
hideturtle()#Hide the brush
setup(500,500)#500×500 square screen
up()#lift the pen
goto(-150,50)#go to the target point
down()# pen down
color("red","red")#The brush is filled with red
seth(90)# change the direction to Celery
begin_fill()#start filling
circle(-75,180)#Draw a semicircle to the right
circle(75,-180)#Draw a semicircle to the right
step = 4.06635
seth(270)#down
for i in range(90):#画卷想恩羽圆
forward(step)# walk step length
step = step - 0.025# gradually reduce the step size
right(1)# turn right 1 degree
for i in range(90):
step = step + 0.025# gradually increase the step size
right(1)# turn right 1 degree
forward(step)# walk step length
end_fill()
The following is the running effect:
a heart

This is a simple version of Snake code. Although the structure is simple, all the necessary functions are complete and the playability is good.
