隨機數生成驗證碼

生成隨機驗證碼，並判斷用戶輸入的驗證碼是否正確

def identifying_code():
    temp = ""
    for i in range(4):
        num = random.randrange(0, 4)
        if num == 1 or num == 3:
            rad1 = random.randrange(0, 9)
            temp = temp + str(rad1)
        elif num == 0 :
            rad2 = random.randrange(65, 91)
            temp = temp + chr(rad2)
        elif num == 2 :
            rad3 = random.randrange(97, 122)
            temp = temp + chr(rad3)
    print "隨機生成的驗證碼是：",temp
    return temp

while True:
    s = identifying_code()
    code = raw_input("請輸入驗證碼（區分大小寫）：")
    if code == s:
        print("恭喜你，驗證碼輸入正確~")
        break
    else:
        print("驗證碼輸入不正確，請從新輸入（已自動刷新驗證碼）")
