如何让程序要求用户输入长度，并使用输入的内容来制作用户想要的密码

Question

#random password generator
import random
unified_code = "awertyuiosqpdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890!@#$%^&*()_+"

passlength1=input("how long should your password be")
pass_length2=input("how long should your password be")

def generatrandompaassword():
    length = random.randint(passlength1,pass_length2 )

    password = "" 

    for index in range(length):
        randomCharacter = random.choice(unified_code)
        password = password + randomCharacter



    return password

passworder = generatrandompaassword()
print(passworder)
print("This is your new password")

由于某种原因，这不会让我发布什么是评论

这是我几天前开始使用Python时编写的代码，所以我对它还很陌生

我尝试放入一个变量，而不是询问用户输入并将输入插入到程序中，然后使用它来查找密码应该有多长的长度可以得到帮助吗？

Answer 1

我重写了你的代码。 您可以阅读评论以了解发生了什么。 本质上，我们有一个将在密码中使用的字符列表。 然后，我们询问用户密码的长度，并将其转换为数字。 之后，我们循环遍历长度并向密码添加随机字符。

import random
characters = "awertyuiosqpdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890!@#$%^&*()_+"

# Get the length of the password, and cast it to an integer so it can be used in the for loop ahead
length = int(input("how long should your password be? "))

def generatrandompaassword():
    password = ""

    # For every character in the password, get a random character and add that to the password
    for i in range(length):
        password += random.choice(characters)

    return password

# Get the password
password = generatrandompaassword()
print("This is your new password: " + password)

Answer 2

代码 - 您的代码需要进行细微更改

# random password generator
import random
unified_code = "awertyuiosqpdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890!@#$%^&*()_+"

pass_length1 = int(input("What should be the min length your password be: "))
pass_length2 = int(input("What should be the max length your password be: "))

def generatrandompaassword():
    length = random.randint(pass_length1, pass_length2 )
    password = "" 
    for index in range(length):
        randomCharacter = random.choice(unified_code)
        password = password + randomCharacter
    return password

passworder = generatrandompaassword()
print(passworder)
print("This is your new password")

您从用户收到的输入是

str

类型，因此您需要将其转换为

int

数据类型。

输出

What should be the min length your password be: 5
What should be the max length your password be: 15

This is your new password

建议：

• 坚持使用

  _

  或驼峰式。

  pass_length1

  和

  randomCharacter 

  有两种风格。
• 尽量让你的函数名称易于理解。使用

  generate_random_password

  而不是

  generatrandompaassword

• 前后给

  =

  留出一些空间。
