【python】生成随机n位数字与字母组合（创建随机）

1.环境

ubuntu
python3.6

random

2.代码 

（1）生成6位数字与字母组合

import random

n = 6

def v_code(n=6):
        """
            Returns:
                ret:random six num and letter
        """
        ret = ""
        for i in range(n):
            num = random.randint(0, 9)
            # num = chr(random.randint(48,57))#ASCII表示数字
            letter = chr(random.randint(97, 122))  # 取小写字母
            Letter = chr(random.randint(65, 90))  # 取大写字母
            s = str(random.choice([num, letter, Letter]))
            ret += s
        return ret

（2）生成6位字母组合

import random

n = 6

def v_code1(n=6):
        """
            Returns:
                ret:random six letter
        """
        ret = ""
        for i in range(n):
            letter = chr(random.randint(97, 122))  # 取小写字母
            Letter = chr(random.randint(65, 90))  # 取大写字母
            s = str(random.choice([letter, Letter]))
            ret += s
        return ret

（3）生成6位数字组合

import random

n = 6

def v_code2(n=6):
        """
            Returns:
                ret:random six num
        """
        ret = ""
        for i in range(n):
            num = random.randint(0, 9)
            s = str(random.choice([num]))
            ret += s
        return ret
