Question

我刚开始学习Python，并为我们的Service Desk（一个密码生成器）启动了一个小项目。它可以工作，但是我希望它能够获取用户输入并创建另一个密码。我已经做了很多搜索并找到了大量的密码生成器，我已经弄清楚如何重复一个密码，但不知道如何在输入上生成新的passowrd。我的代码如下，将在输入时重复输入密码。任何帮助将不胜感激。

    import random

alphabet = "abcdefghijklmnopqrstuvwxyz"
pw_length = 6
mypw = ""

for i in range(pw_length):
    next_index = random.randrange(len(alphabet))
    mypw = mypw + alphabet[next_index]

# replace 1 or 2 characters with a number
for i in range(random.randrange(1,3)):
    replace_index = random.randrange(len(mypw)//2)
    mypw = mypw[0:replace_index] + str(random.randrange(10)) + 
mypw[replace_index+1:]

# replace 1 or 2 letters with an uppercase letter
for i in range(random.randrange(1,3)):
    replace_index = random.randrange(len(mypw)//2,len(mypw))
    mypw = mypw[0:replace_index] + mypw[replace_index].upper() + 
mypw[replace_index+1:]

print("Your password is" + (mypw))
inp = input()
while inp != "":
    print(mypw)
    inp = input()

Answer 1

你必须通过将所有内容放入while循环来重复密码生成，或者更好，编写一个函数来生成一个密码并在while循环中调用此函数：

import random

alphabet = "abcdefghijklmnopqrstuvwxyz"
pw_length = 6

def generate_password(pw_length):
    mypw = ""
    for i in range(pw_length):
        next_index = random.randrange(len(alphabet))
        mypw = mypw + alphabet[next_index]

    # replace 1 or 2 characters with a number
    for i in range(random.randrange(1,3)):
        replace_index = random.randrange(len(mypw)//2)
        mypw = mypw[0:replace_index] + str(random.randrange(10)) + 
    mypw[replace_index+1:]

    # replace 1 or 2 letters with an uppercase letter
    for i in range(random.randrange(1,3)):
        replace_index = random.randrange(len(mypw)//2,len(mypw))
        mypw = mypw[0:replace_index] + mypw[replace_index].upper() + 
    mypw[replace_index+1:]
    return mypw

while True:
    print("Your password is", generate_password(pw_length))
    inp = input()
    if not inp:
        break

或略微优化的版本：

import string
import random

def generate_password(pw_length):
    charsets = []
    # take 1 or 2 numbers
    for i in range(random.randrange(1,3)):
        charsets.append(string.digits)
    # take 1 or 2 uppercase
    for i in range(random.randrange(1,3)):
        charsets.append(string.ascii_uppercase)
    # fill up with lowercase up to pw_length
    while len(charsets) < pw_length:
        charsets.append(string.ascii_lowercase)
    # generate password of charsets
    random.shuffle(charsets)
    return ''.join(random.choice(cs) for cs in charsets)

while True:
    print("Your password is", generate_password(pw_length))
    inp = input()
    if not inp:
        break

不幸的是无法评论我的评分，但我猜哈希输入会有效吗？因为它产生一个随机的＆＃39;串。另外，散列是一种存储密码的好方法。

def Generate_Password():
    input_ = input('please enter your password: ')
#i saw you have a limit of length 6, but you can tweak it
    if len(input_) > 6:
        print ('Max length for a pssword is 6')
    hashPassword = hashlib.sha3_256(b'{input_}').hexdigest()
    return (hashPassword)

生成密码密码需要全部字符组合

类密码： def init （自己）：＃self.choice =选择 self.menu = {1：“生成通行证”，3：“退出”} def main（self）：对于self.menu.items（）中的x，y：打印x，y #print'\ n' #print'选择一个\ n' 打印'\ n' 尝试： self.choice = int（raw_input（“输入选择：”））除了： print（“没有有效的整数！请尝试...”）
self.main（） self.check（）

def check(self):
    #print 'select one\n'
    if self.choice == 1:
        self.genpass()  
    elif self.choice == 3:
        self.exi(exit)
    else:
        print 'invalid entry try again' 
        self.main()
        #print 'invalid'

def genpass(self):
    import random
    import re
    import string 
    min_len = 8
    max_len = 12
    self.passlen = random.randint(min_len, max_len)
    #s = "@4A%1aXb6!B2#8lZ$t5&"
    #random.shuffle(s)
    #password =  "".join(random.sample(s,passlen))
    #print 'Generate password \n', password, '\n'

    self.password1 = ""
    SpecialChars = "!@#$%%^*"
    self.password1 += random.choice(string.ascii_uppercase)
    self.password1 += random.choice(string.ascii_lowercase)
    self.password1 += random.choice(string.digits)
    self.password1 += random.choice(SpecialChars)
    for i in range(0,self.passlen):
        self.password1 += random.choice(string.ascii_uppercase +
          string.ascii_lowercase + 
          string.digits+
          SpecialChars)
    self.all_symbol = ''.join(random.sample(self.password1,self.passlen))
    flag =0
    while True:   
        if not re.search("[a-z]", self.all_symbol): 
            flag = -1
            break
        elif not re.search("[A-Z]", self.all_symbol): 
            flag = -1
            break
        elif not re.search("[0-9]", self.all_symbol): 
            flag = -1
            break
        elif not re.search("[_@$]", self.all_symbol): 
            flag = -1
            break
        elif re.search("\s", self.all_symbol): 
            flag = -1
            break
        else: 
            flag = 0
            print 'password Length\t', self.passlen
            print 'Generate password is\t', self.all_symbol, '\n'
            break

    if flag ==-1: 
        self.genpass()




        #print len(password)
def exi(self, exit):
    import sys
    sys.exit()

为True时： p =密码（） p.main（）
