Hello everyone, the editor will answer the following questions for you, python draws specific explosion effects of fireworks, python code draws dynamic fireworks, let's take a look today!
1. What is the source code of Python Cool Fireworks Confession? _ Baidu know
After finishing this tutorial, you can also make such a firework show.
As shown above, here we simulate the explosion effect by splitting a particle on the screen into X number of particles. The particles "expand," meaning they move at a constant speed and at equal angles to each other. This allows us to simulate the fireworks blooming as an outwardly expanding circle.
After a certain amount of time, the particles will enter the "" stage, that is, they will start to fall to the ground due to gravity, like fireworks that bloom and then go out.
The Basics: Design Fireworks with Python and Tkinter.
Here we no longer throw out all the mathematical knowledge in one brain, we write code and talk about theory. First, make sure you have installed and imported Tkinter, which is Python's standard GUI library and is widely used in various projects and program development. Using Tkinter in Python can quickly create GUIs.
import tkinter as tk
from PIL import Image, ImageTk
from time import time, sleep
from random import choice, uniform, randint
from math import sin, cos, radians
In addition to Tkinter, in order to make the interface have a beautiful background, we also import PIL for use, and import some other packages, such as time, random and math. They allow us to more easily control the trajectory of fireworks particles.
The basic setup for a Tkinter application is as follows:
root = ()
In order to initialize Tkinter, we must create a Tk() root widget, which is a window with a title bar and other decorations provided by the window manager. The root widget must be created before we create other widgets, and there can only be one root widget.
w = tk.Label(root, text="岁腊Hello Tkinter!")
This line of code contains the Label widget. The first parameter in the Label call is the name of the parent window, which is the "root" we use here. The keyword argument "text" specifies the text content to display. You can also call other widgets: Button, Canvas, etc.
w.pack()
root.mainloop()
The next two lines of code are important. The packing method here is to tell Tkinter to resize the window to fit the widget used. The window doesn't appear until we enter the Tkinter event loop, which is called by root.mainloop(). The script will stay in the event loop until we close the window.
Translate Fireworks Blooms to code
Now we design an object to represent each particle in the fireworks event. Each particle will have some important properties that govern its appearance and movement: size, color, position, speed, etc.
2. Confession fireworks code_Baidu Know
Friends who type code every day, have you ever thought that code can also become cool and romantic? Today I will teach you to use Python to simulate blooming fireworks. After work, you can also let the program put a firework show for yourself at any time and use python to draw a full screen of fireworks .
Python Cool Firework Watch Town Wang Pants White Source Code
This interesting little project is not complicated, just a little visualization skills, more than 100 lines of Python code and the program library Tkinter, and finally we can achieve the following effect: after finishing this tutorial, you can also make such a
fireworks show.
Overall concept review
Our overall concept is relatively simple.
Here we simulate the explosion effect by splitting a particle on the screen into X number of particles. The particles "expand," meaning they move at a constant speed and at equal angles to each other. This allows us to simulate the fireworks blooming as an outwardly expanding circle. After a certain amount of time, the particles will enter the "free fall" stage, that is, they will start to fall to the ground due to gravity, like fireworks that bloom and then go out.

4. How to draw with python_Baidu Know
You can use the two libraries numpy and matplotlab to realize your function.
You can refer to the friend map:
import matplotlib from 咐敏携numpy.random import randn import matplotlib.pyplot as plt from matplotlib.ticker import FuncFormatter def to_percent(y, position): # Ignore the passed in position. This has the effect of scaling the default # tick locations. s = str(100 * y) # The percent symbol needs escaping in latex if matplotlib.rcParams['text.usetex'] == True: return s + r'$\%$' else: return s + '%' x = randn(5000) # Make a normed histogram. It'll be multiplied by 100 later. (x, bins=50, normed=True) # Create the formatter using the function to_percent. This multiplies all the # default labels by 100, making them all percentages formatter = FuncFormatter(to_percent) # Set the formatter ().yaxis.set_major_formatter(formatter) ()
The most important thing is the processing of the x-axis and y-axis. I calculated the data you provided according to the logarithm, and it seems that the effect is different from this picture.
Please accept if it solves your problem!
If it is not resolved by the balance, please continue to ask
5. How to write this question in python? _ Baidu know
You can use the following Python code to solve this problem:
```python
def consume_gold(N, M, gold):
count = 0
total_gold = 0
for i in range(N):
total_gold += gold[i]
if total_gold > M:
count += 1
total_gold = 0
return count
# input processing
N, M = map(int, input().s plit())
gold = list(map(int, input().split()))
# Call the function to calculate the number of consumption
result = consume_gold(N, M, gold)
# Output the result
print(result)
```
This code defines a function named `consume_gold` to calculate the number of consumption. In the main program, first read the input N, M and the number of rough gold coins, and then call the function to calculate the consumption times and print out the result.
I hope the above code is helpful to you!
6. Use Python to realize the following questions, thank you_Baidu Know
The first question, use input() to accept user input, int() to convert the input into an integer, and the statement to judge the condition. The number that can be divisible by 2 is even, otherwise odd number code: n=int(input())ifn%2==0: .. # The dot in front means indentation.
Programming calculation: How many 4-digit numbers have the unit digit of 7 and can be divisible by 3.
Arithmetic sequence, the tolerance is 4, starting from 1, every 4 values are taken for product calculation, count is used for counting, and the cycle ends when it reaches 20.
It should be noted that this parity check can only detect an even number of errors in the binary number, and cannot detect an odd number of errors. At the same time, this verification method cannot correct errors, but only detects the existence of errors.
)}===The program first reads in the input date, and then uses Python's datetime library to convert it into the English abbreviation of the week. Finally, use the center method of the mountain hunger spring string to center the abbreviation and decorate it with two equal signs.

How to draw a May Day poster with python
To draw a May Day poster with Python, you need to use Python's drawing library, such as matplotlib, Pillow, etc. Here is a simple example showing how to use Python and the Pillow library to make a May Day poster:
fromPILimportImage,ImageDraw,ImageFont
#Create a blank canvas with a size of 800x600 and a white background color
canvas=('RGB',(800,600),(255,255,255))
#Add May Day greetings to the canvas
font=('',48)#Set font style and size
draw=(canvas)
((200,100),'Happy May Day!',fill=(0,0,0),font=font)#Set text position, color and font
#Add the five-star red flag pattern on the canvas
flag=('')#Read the five-star red flag picture
flag=((200,133))#Set the picture size to 200x133
(flag,(300,300))#Paste the picture to the canvas
#Save and display the canvas
('')
()
In this example, we first use the Pillow library to create a blank canvas with a size of 800x600, and add May Day greetings and five-star red flag patterns to the canvas. Finally, use the save() method to save the canvas as an image in PNG format, and use the show() method to display the image. In actual operation, you need to modify the code according to your needs, such as changing the greeting, adjusting the font size and color, changing the picture, etc.

It bundles a lot of tools for bitmap editing, display, Web graphics, and vector drawing in the clip gallery. Because canvas seamlessly integrates functions for vector illustration, image editing, and Web publishing, it is the best and is loved by a large number of users.
8. In Python, what statement can be used to define a function as an argument that takes over a variable? _ Baidu know
In Python, if you want to define a function that can receive a variable number of parameters, you can use the special symbol * (single asterisk) as the prefix of the parameter list when the function is defined, for example: ```python def my_function(*args): # function body part```This *args means that the parameter list can
receive
0 or
more . The parameters are in the function body, and each parameter in the parameter list can be accessed like an ordinary tuple. For example, args[0] means access to the first parameter. If you want to define a function that can receive a variable number of keyword parameters, you can use a special symbol ** (double asterisk) as the prefix of the parameter list, for example: ```python def my_function(**kwargs): # function body part```This **kwargs means that the parameter list can receive 0 or more keyword parameters. In the function body, each keyword parameter in the parameter list can be accessed like an ordinary dictionary (dict). For example, kwargs['name'] means to access the parameter named 'name' among the keyword parameters. It should be noted that in the function definition, *args and **kwargs can appear together with other parameters representing named parameters, but *args must appear before **kwargs.
