# 生成4位随机小写字母
str_s = ""
for i in range(4):
    num_1 = random.randrange(97,123)
    zimu = chr(num_1)
    str_s = str_s + zimu
# print(str_s)

# 生成8位随机数字
str_n = ""
for i in range(8):
    num_2 = random.randrange(0,10)
    num_3 = str(num_2)
    str_n = str_n + num_3
# print(str_n)

print(str_s + str_n)
