所以我想寫一個 Python 代碼，為用戶創建一個隨機密碼。它需要詢問用戶他們希望密碼多長，并且有最少的字符集。幾個星期以來，我一直在努力尋找一些東西，但就是找不到，如果這個問題已經解決了，我深表歉意。這是我到目前為止的代碼，不知道我需要什么其他代碼以及我必須在哪里使用才能獲得我想要的東西。import randomimport secretsimport string# This variable includes numbersdigits = string.digits# This variable includes uppercase and lowercase lettersletters = string.ascii_lowercase# This variable includes symbolssymbols = "!#$%&'()*+, -./:;<=>?@[\]^_`{|}~"password = ''.join(secrets.choice(digits + letters + symbols) for t in range(20))def message(): print("Hello, here is a password generator: ") print("Choose the length?") print(userGen())def userGen(): upper = int(input("How many letters you want? ")) spec = int(input("How many symbols you want? ")) num = int(input("How many numbers you want? ")) return passGen(upper,spec,num)def passGen(upper,spec,num): new_password = "" for i in range(upper): new_password += random.choice(letters) for x in range(spec): new_password += random.choice(symbols) for y in range(num): new_password += random.choice(digits) pass_word = list(new_password) shuff = random.shuffle(pass_word) new_pass = "".join(pass_word) password = secrets.token_urlsafe(7) return new_passmessage()

用這個改變你的 userGen() ：
def userGen():
c = 0
upper = int(input("How many letters you want? "))
spec = int(input("How many symbols you want? "))
num = int(input("How many numbers you want? "))
c += upper + num +spec
if c < 7:
print('Your password is too short.')
userGen()
else:
return passGen(upper,spec,num)
編輯：
import random
import string
import secrets
length = 7
# This variable includes numbers
digits = "1234567890"
# This variable includes uppercase and lowercase letters
letters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
# This variable includes symbols
symbols = "!#$%&'()*+, -./:;<=>?@[\]^_`{|}~"
password = ''.join(secrets.choice(digits + letters + symbols) for t in range(20))
def message():
print("Hello, here is a password generator. ")
print("Choose the length of your characters:")
passGen()
def passGen():
c = 0
upper = int(input("How many letters you want? "))
spec = int(input("How many symbols you want? "))
num = int(input("How many numbers you want? "))
c += upper + num +spec
if c < length:
print('Your password is too short.')
passGen()
else:
new_password = ""
for i in range(upper):
new_password += random.choice(letters)
for x in range(spec):
new_password += random.choice(symbols)
for y in range(num):
new_password += random.choice(digits)
pass_word = list(new_password)
shuff = random.shuffle(pass_word)
new_pass = "".join(pass_word)
password = secrets.token_urlsafe(7)
print(new_pass)
message()

我相信你想要完成的事情可以用一個簡單的if語句來完成。你想要：
檢查用戶是否輸入了最多 7 個字符的組合
如果那是真的：
像您目前正在做的那樣分配密碼
如果不是這樣，您至少有兩個選擇：
像@Ktoto 建議的那樣打印一條錯誤消息
通過自己設置字母、數字和符號的數量來強制密碼至少為 7 個字符。

您可以像這樣使用 if 語句：
def userGen():
upper = int(input("How many letters you want? "))
spec = int(input("How many symbols you want? "))
num = int(input("How many numbers you want? "))
if int(upper) + int(spec) + int(num) <= 7:
# your code
return passGen(upper, spec, num)
然后向您喜歡的特定類型的字符添加更多字符。

如果用戶的選擇加起來不夠，這個問題并不清楚應該添加什么樣的字符，所以我建議你只是讓用戶再試一次，直到有足夠的為止。
雖然嚴格來說不是問題的答案，但這里有一些關于您可以執行的代碼一般整理的建議。它包括兩個字典的使用：characters一個保存字符的類型，另一個choices保存用戶對每種類型項目的數量的選擇。如果您想更改內容，例如將“字母”拆分為大寫和小寫的單獨計數，那么您只需要更改頂部的字典。
import random
characters = {'digits': '1234567890',
'letters': 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',
'symbols': "!#$%&'()*+,-./:;<=>?@[\]^_`{|}~"}
def getChoices(min_total=7):
print('Hello, here is a password generator: ')
print('Choose the length of your characters?')
while True:
total = 0
choices = {}
for category in characters.keys():
number = int(input(f'How many {category} do you want? '))
choices[f'num_{category}'] = number
total += number
if total >= min_total:
return choices
else:
print(f'Need at least {min_total} characters - please try again')
def passGen(choices):
new_password = ''
for category, options in characters.items():
for i in range(choices[f'num_{category}']):
new_password += random.choice(options)
pass_word = list(new_password)
random.shuffle(pass_word)
new_pass = ''.join(pass_word)
return new_pass
def main():
choices = getChoices()
print(f'Your choices: {choices}')
password = passGen(choices)
print(f'Your password: {password}')
main()
