Getting error when I run my program. What do I need to change?
问题
导入 random，string
字符串 = string.ascii_letters + string.digits + string.punctuation
def 生成随机密码():
长度 = int(input("密码有多少个字符？"))
密码数量 = int(input("您想要多少个密码？"))
字符计数 = 字符串
if 字符计数 > str(长度):
print("太长了，请重试")
return
密码 = []
for i in range(长度):
密码.append(random.choice(字符串))
if 字符计数 < str(长度):
random.shuffle(字符串)
for i in range(长度 - 字符计数):
密码.append(random.choice(字符串))
random.shuffle(密码)
输出 = "".join(密码)
print(输出)
return(输出)
结果 = 生成随机密码()
with open("pwd.txt", "w+") as 文件:
文件.write(结果)
英文:
import random, string
characters = string.ascii_letters + string.digits + string.punctuation
def generate_random_password():
length = int(input("How many characters in password? "))
number_of_passwords = int(input("How many passwords would you like? "))
character_count = characters
if character_count > str(length):
print("To long, try again")
return
password = []
for i in range(length):
password.append(random.choice(characters))
if character_count < str(length):
random.shuffle(characters)
for i in range(length - character_count):
password.append(random.choice(characters))
random.shuffle(password)
output = "".join(password)
print(output)
return(output)
results = generate_random_password()
with open("pwd.txt", "w+") as file:
file.write(results)
This the code for the generator and when I get to the end the result is the same:
file.write(results)
TypeError: write() argument must be str, not None
I tried the str function and int function; I changed "w+" to "a". I thought using the str function would fix it, considering the argument must be str.

代码现在可以运行。我编辑了它，这样你就可以生成指定长度的密码了。现在轮到你完成代码，使其能够生成多个密码。
import random, string
characters = list(string.ascii_letters + string.digits + string.punctuation)
def generate_random_password():
length = int(input("密码长度是多少个字符？\n"))
number_of_passwords = int(input("你想要生成多少个密码？\n"))
character_count = len(characters)
if length > character_count:
print("太长了，请重试")
return -1
password = []
output = ""
for i in range(number_of_passwords):
output = "".join(random.sample(characters, length))
password.append(output)
print(output)
return password
results = generate_random_password()
if results != -1:
with open("pwd.txt", "w+") as file:
for pwd in results:
file.write(pwd + "\n")

Code is now runnable. I edited it so that you can now generate a password of a specific length. Now, it's up to you to complete the code so that it can generate more than 1 password.
import random, string
characters = list(string.ascii_letters + string.digits + string.punctuation)
def generate_random_password():
length = int(input("How many characters in password?\n"))
number_of_passwords = int(input("How many passwords would you like?\n"))
character_count = len(characters)
if length > character_count:
print("Too long, try again")
return -1
password = []
output = ""
for i in range(length):
output += "".join(random.sample(characters, length))
password.append(output)
print(output)
return (output)
results = generate_random_password()
if results != -1:
with open("pwd.txt", "w+") as file:
file.write(results)

在接受用户输入时，需要确保输入的数据类型是特定类型（在本例中是int），您应该始终进行验证。
函数应该按照它们的名称建议的方式执行——没有更多。
random 模块具有一个choices() 函数，非常适合您的需求。
from random import choices
from string import ascii_letters, digits, punctuation
CHARACTERS = ascii_letters + digits + punctuation
def generate_random_password(length):
return ''.join(choices(CHARACTERS, k=length))
while True:
try:
if (length := int(input('密码有多少个字符？ '))) > len(CHARACTERS):
raise Exception(f'最大长度为{len(CHARACTERS)}')
password = generate_random_password(length)
with open('pwd.txt', 'w') as pwd:
pwd.write(password)
break
except Exception as e:
print(e)
英文:
When taking user input that needs to be of a certain type (in this case int) you should always validate it.
Functions should do what their name suggests - nothing more.
The random modules has a choices() function which is ideal for your needs.
from random import choices
from string import ascii_letters, digits, punctuation
CHARACTERS = ascii_letters + digits + punctuation
def generate_random_password(length):
return ''.join(choices(CHARACTERS, k=length))
while True:
try:
if (length := int(input('How many characters in password? '))) > len(CHARACTERS):
raise Exception(f'Maximum length is {len(CHARACTERS)}')
password = generate_random_password(length)
with open('pwd.txt', 'w') as pwd:
pwd.write(password)
break
except Exception as e:
print(e)
