random实现验证码 

 1 import random
 2 # c = []
 3 # for i in range(5):
 4 #     a = random.randint(0,9)
 5 #     b = chr(random.randint(65,90))
 6 #     c.append(random.choice((a,b)))
 7 # print(c, end='')
 8 
 9 # 2
10 
11 # c = []
12 # for i in range(5):
13 #     a = random.randint(0,9)
14 #     b = chr(random.randint(65,90))
15 #     c.append(random.choice((a,b)))
16 # s = ''
17 # for j in c:
18 #     s += str(j)
19 # print(s)
20 
21 # 3 chr(30)----返回的是字符串
22 s = ''
23 for i in range(5):
24     a = random.randint(0,9)
25     b = chr(random.randint(65,90))
26     c = str(random.choice((a,b)))
27     s += c
28 print(s)
