如何让程序要求用户输入长度并使用输入来生成密码，只要用户愿意

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")

这不会让我出于某种原因发表什么是评论

这是我几天前开始使用 python 编写的代码，所以我对它很陌生

首先，我尝试放置一个变量，而不是要求用户输入并将输入插入程序并使用它来查找密码应该多长的长度可以获得帮助吗？

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，我们遍历长度并向密码添加一个随机字符。

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 - 您的代码需要稍作改动

# 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")

您从用户那里收到的输入是str类型的，因此您需要将其转换为int数据类型。

Output

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 camelCasing。 pass_length1和randomCharacter是两个 styles。
• 尽量使您的函数名称易于理解。 使用generate_random_password不是generatrandompaassword
• 在=前后给一些空间。

阅读一些关于 python PEP 标准的内容，使您的代码更具可读性。
