本文实例讲述了python3生成随机数的方法。分享给大家供大家参考。具体实现方法如下:
该实例是根据一本书上看到过一个随机数的小程序,经过自己改动,变为了一个猜数字的小游戏,现在在python3下重写了一遍。
这是一个控制台下的猜数程序,winxp+python3.2+eric5和IDLE测试通过,但直接用winxp的命令行运行有问题,原因还未知,慢慢找。ubuntu+python3.1测试通过。
具体实现代码如下:
# -*- coding: utf-8 -*- import Image,ImageDraw,ImageFont import random import math, string class RandomChar(): """用于随机生成汉字""" @staticmethod def Unicode(): val = random.randint(0x4E00, 0x9FBF) return unichr(val) @staticmethod def GB2312(): head = random.randint(0xB0, 0xCF) body = random.randint(0xA, 0xF) tail = random.randint(0, 0xF) val = ( head << 8 ) | (body << 4) | tail str = "%x" % val return str.decode('hex').decode('gb2312') class ImageChar(): def __init__(self, fontColor = (0, 0, 0), size = (100, 40), fontPath = 'wqy.ttc', bgColor = (255, 255, 255), fontSize = 20): self.size = size self.fontPath = fontPath self.bgColor = bgColor self.fontSize = fontSize self.fontColor = fontColor self.font = ImageFont.truetype(self.fontPath, self.fontSize) self.image = Image.new('RGB', size, bgColor) def rotate(self): self.image.rotate(random.randint(0, 30), expand=0) def drawText(self, pos, txt, fill): draw = ImageDraw.Draw(self.image) draw.text(pos, txt, font=self.font, fill=fill) del draw def randRGB(self): return (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)) def randPoint(self): (width, height) = self.size return (random.randint(0, width), random.randint(0, height)) def randLine(self, num): draw = ImageDraw.Draw(self.image) for i in range(0, num): draw.line([self.randPoint(), self.randPoint()], self.randRGB()) del draw def randChinese(self, num): gap = 5 start = 0 for i in range(0, num): char = RandomChar().GB2312() x = start + self.fontSize * i + random.randint(0, gap) + gap * i self.drawText((x, random.randint(-5, 5)), RandomChar().GB2312(), self.randRGB()) self.rotate() self.randLine(18) def save(self, path): self.image.save(path)
希望本文所述对大家的Python程序设计有所帮助。
