一行Python生成随机字符串

一行Python代码生成随机字符串：

import random, string; print(''.join(random.choice(string.ascii_letters + string.digits) for _ in range(15)))

# python -c "import random, string; print(''.join(random.choice(string.ascii_letters + string.digits) for _ in range(15)))"

如果是Python3，还可以使用：

import random, string; print(''.join(random.choices(string.ascii_letters + string.digits, k=15)))

# python3 -c "import random, string; print(''.join(random.choices(string.ascii_letters + string.digits, k=15)))"
