生成随机的验证码图片（Python）

---

一、导入包

import random
from PIL import Image, ImageDraw, ImageFont

二、生成随机的验证码

def random_code(length=4):'''默认返回4位随机验证码，字符串'''code = ""characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"for i in range(length):rand_char = random.choice(characters)code += rand_charreturn code

三、生成随机的rgb颜色

def random_color():"""默认返回随机颜色，元组"""return random.randrange(256), random.randrange(256), random.randrange(256)

四、生成图片验证码

def image_code(width=120, height=30, point=100, line=4):'''生成图片验证码'''code = random_code()color = random_color()image = Image.new(mode='RGB', size=(width, height), color=(0, 0, 0))  # 背景图片draw = ImageDraw.Draw(image)font = ImageFont.truetype("arial.ttf", 28)  # 字体for i, ch in enumerate(code):draw.text([i * width / 4, 0], ch, fill=color, font=font)for _ in range(point):draw.point([random.randint(0, width), random.randint(0, height)], fill=random_color())  # 画点for _ in range(line):draw.line((random.randint(0, width),random.randint(0, height),random.randint(0, width),random.randint(0, height)),fill=random_color())  # 画线image.show()# image.save(r'')
