Verification code

# python 实现验证码

import random

while  count<n:
    count+=1
    lis.append(str(random.randint(0,9)))
    lis.append(chr(random.randint(65,90)))
    lis.append(chr(random.randint(97,122)))

lis2 = random.sample(lis,n)
print(lis2)

lis1 = ''.join(lis2)
print(lis1)
# for i in lis2:
#     print(i,end=' ')

progress bar
