[Python知识库]Pygame简单入门学习笔记

首先先放出我的第一个使用Pygame写的程序“菜虚鲲大战蔡徐坤”。?

import random
import pygame
import sys
import time
pygame.init()#初始化
#主窗口
screen_image = pygame.display.set_mode((800,600))#设置分辨率
screen_rect = screen_image.get_rect()

#标题栏
pygame.display.set_caption('人工智能2x0xXXX2021xxxxxx')#设置文件名

#飞船
ship_image = pygame.image.load('image/cai1.bmp')
ship_rect = ship_image.get_rect()
ship_rect.center = screen_rect.center#居中对齐

#子弹1
bullet_rect = pygame.Rect(0,0,3,15)
bullet_rect.midbottom = ship_rect.midtop
bullet_rect.x=0
bullet_rect.y=0

#散弹枪
grape_rect = pygame.Rect(0,0,3,15)
grape_rect.midbottom=ship_rect.midtop
grape_rect.x=bullet_rect.x+5
grape_rect.x=0
grape_rect.y=0

#怪物

monster_image = pygame.image.load('image/cai2.bmp')
monster_rect = ship_image.get_rect()
monster_rect.x = 360

#文字
txt_font = pygame.font.SysFont(None,48)
txt_image = txt_font.render('caixukun',True,(60,60,60),(255,0,0))
txt_rect = txt_image.get_rect()


while True:
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            sys.exit()
        elif event.type==pygame.KEYDOWN:

            if event.key == pygame.K_k:
                #bullet_rect.midbottom = ship_rect.midtop
                grape_rect.midbottom = ship_rect.midtop
                grape_rect.x+=10

    # if monster_rect.x == bullet_rect.x or monster_rect.y == bullet_rect.y:
    #     monster_rect.y = 0
    #     monster_rect.x +=10
    #     pass
    # if monster_rect.y-bullet_rect.y<=10:
    #     if bullet_rect.x <= monster_rect.x:
    #         monster_rect.x+=1
    #         pass
    #     elif bullet_rect.x > monster_rect.x:
    #         monster_rect.x-=1
    #     pass
    if abs(monster_rect.x-bullet_rect.x)<=100 and abs(monster_rect.y-bullet_rect.y)<=100:
        bullet_rect.y = 0
        monster_rect.y=0
        monster_rect.x = random.randint(0,600)
        pass

    monster_rect.y+=1
    bullet_rect.y-=20
    grape_rect.y-=1
    time.sleep(0.05)
    #绘制图像
    screen_image.fill((0,128,128))#设置背景颜色
    screen_image.blit(ship_image,ship_rect)#设置飞船
    screen_image.blit(monster_image,monster_rect)
    pygame.draw.rect(screen_image,(60,60,60),bullet_rect)
    pygame.draw.rect(screen_image,(80,80,80),grape_rect)
    screen_image.blit(txt_image,txt_rect)
    pygame.display.flip()#刷新

我在学习python的时候，学习的方向以及顺序都跟去年学习C++差不多，大致就是先从输入输出开始，然后是基本的语句，字典、列表、元组等等，然后是文件输入输出以及类与对象、继承多态等等。

这其中有很多知识我都是早早学完了，python我在去年就把基础的知识学的差不多了，Scott自学python——字符串学习笔记_轩Scott的博客-CSDN博客

Scott自学python——字典学习笔记_轩Scott的博客-CSDN博客

Scott自学python——元组学习笔记_轩Scott的博客-CSDN博客

Scott自学python——列表学习笔记_轩Scott的博客-CSDN博客

这些都是我以前学习python的博客笔记。

暑假期间我主要是学习了pygame和python的文件输入输出以及类与对象、继承多态等等，以下是我在练习中写的核酸检测登记系统

import datetime
import csv
class Nuclear_Test():#核酸检测结果
    def __init__(self,id):
        self.time = datetime.datetime.now()

    def Output(self):
        print('Nuclear test time is',self.time,',result=',self.result)
    pass

class Person():#核酸检测人员信息
    def __init__(self,name,id):
        self.name = name#名
        self.id = id#身份证号

        pass

        index = Nuclear_Test(self.id)
        index.result=result
        self.Nuclear.append(index)
        self.Nuclear_Number+=1
        pass

    def Output(self):

?知识不用罗列，全部呈现在代码中了。

现在我们有一组从2006年到2016年1000部最流行的电影数据，
数据来源:https://www.kaggle.com/damianpanek/sunday-eda/data
（数据是本文件下的 IMDB-Movie-Data）
·问题1:我们想知道这些电影数据中评分的平均分，导演的人数等信息，我们应该怎么获
取?
·问题2∶对于这一组电影数据，如果我们想rating，runtime的分布情况，应该如何呈现数
据?
·问题3∶对于这一组电影数据，如果我们希望统计电影分类(genre)的情况，应该如何处理数据?

?问题1

import numpy as np
import pandas as pd
import csv
import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

imdb = pd.DataFrame(pd.read_csv('IMDB-Movie-Data.csv'))
rating = imdb['Rating'].values
print('电影数据中评分的平均分 ' , rating.mean())

dir=imdb['Director'].values
director = list(set(dir))
print('导演的人数 ',len(director))
