## （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
