1、验证码生成案例：
#!/usr/bin/env python import random code=[] for i in range(6): if i == random.randint(1,5): code.append(str(random.randint(1,9))) else: temp = random.randint(65,90) code.append(chr(temp)) #chr转化成字母 print(‘‘.join(code)) #格式化成字符串
2、线程和进程对比
from multiprocessing import Process,Queue
import threading
def run(info_list,n):
info_list.append(n)
print(info_list)
info = []
if __name__ == ‘__main__‘:
for i in range(12):
p = Process(target=run,args=[info,i])
p.start()
print(‘--------------------------‘)
if __name__ == ‘__main__‘:
for i in range(12):
p = threading.Thread(target=run, args=[info, i])
p.start()
