制作随机验证码,需要如下知识点: 1.随机验证码的制作(这里用的是random模块随机产生字符) 2.图片的制作 3.随机直线干扰项 4.其他随机干扰项 代码如下: from PIL import Image from PIL import ImageDraw from PIL import ImageFont import random #随机颜色 def get_random_color(): r = random.randint(0,255) g = random.randint(0,25…
public class Demo5 { public static void main(String[] args) { char[] arr={'s','b','g','h','a','c'}; StringBuilder sb=new StringBuilder(); Random random=new Random(); for(int i=0;i<4;i++){ int index=random.nextInt(arr.length); sb.append(arr[index]); }…
import random checkcode = '' for i in range(4): if i == random.randint(0,3): current = chr(random.randrange(65,90)) checkcode += str(current) else: checkcode += str(i) print(checkcode)…
