python生成隨機(jī)n位數(shù)字與字母組合

環(huán)境

ubuntu
python3.6
random

代碼

（1）生成6位數(shù)字與字母組合

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表示數(shù)字
            letter = chr(random.randint(97, 122))  # 取小寫字母
            Letter = chr(random.randint(65, 90))  # 取大寫字母
            s = str(random.choice([num, letter, Letter]))
            ret += s
        return ret

（2）生成6位字母組合

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))  # 取小寫字母
            Letter = chr(random.randint(65, 90))  # 取大寫字母
            s = str(random.choice([letter, Letter]))
            ret += s
        return ret

（3）生成6位數(shù)字組合

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

結(jié)果樣例：

python批量生成隨機(jī)密碼

需求：一次生成多個(gè)隨機(jī)密碼，密碼強(qiáng)度：包含數(shù)字、大小寫字母，18位。

import random
import string
# 先介紹下random怎么生成隨機(jī)數(shù)和字母
# 產(chǎn)生一個(gè)隨機(jī)整數(shù)
num = random.randint(0,10000)
print(num)
# 產(chǎn)生一個(gè)隨機(jī)字母，注意是一個(gè)
str1 = random.choice(string.ascii_letters)
print(str1)
# 生成10個(gè)、18位隨機(jī)密碼，包含數(shù)字和字母大小寫
def genPass(length):
    # string.ascii_letters: 生成a-Z字母
    # string.digits：生成0-9的數(shù)字字符串
    chars = string.ascii_letters + string.digits
    # 這個(gè)的意思是：從chars中獲取一個(gè)隨機(jī)的字符，這個(gè)字符可能是數(shù)字也可能是大小寫的字母
    # 然后for循環(huán)獲取18次，再用join合并成一個(gè)字符串，所以就成了一個(gè)18位的密碼
    return ''.join([random.choice(chars) for i in range(length)])
if __name__ == '__main__':
    # 批量生成10個(gè)密碼
    for i in range(10):
        print(genPass(18))
