验证码:
1. 生成四位数字验证码
import random check_code = '' for i in range(4):
current = random.randint(0, 9)
check_code = "%s%s" % (check_code, str(current)) print(check_code)
2. 生成六位数字字母的验证码
import random check_code = '' for i in range(6):
current = random.randint(0, 4)
if current != i:
tmp = str(chr(random.randint(65, 90))) #65-90是字母的ASCII码
else:
tmp = str(random.randint(0, 9))
check_code = "%s%s" % (check_code, tmp)
print(check_code)
