如何在 运行 期间使用这些值验证用户输入
How to validate user input while running a while with those values
我正在编写一个密码生成器，它要求用户输入 LENGHT 密码并生成那么长的密码（有效）
问题：我确实验证了用户输入 (while/try/except)，它得到了正确的值错误，它得到了正确的最小长度，但它没有占用最大值值并始终生成长度加上新长度的相同密码。
也许一些例子会有所帮助
from random import randint
lowerCase = "abcdefghijklmnopqrstuvwxyz"
upperCase = lowerCase.upper()
numbers = "1234567890"
special = "!#$%&/()=?¡@[]_<>,."
password_creation = lowerCase + upperCase + numbers + special
password = ""
lenght = 0
while True
try:
password_lenght = int(input("How many characters do you wish the password? Minimum 8 maximum 1024: "))
if password_lenght < 8 or password_lenght > 1024:
print("Minimun 8 characters - maximum 1024, try again")
except ValueError:
print ("Please enter a valid NUMBER...")
continue
else:
while lenght < password_lenght:
password = password + password_creation[randint(0, len(password_creation) -1)]
lenght +=1
print("Generated password: ", password)
如果我 运行 这段代码可以工作：
>>> %Run z_strong_password_gen.py
How many characters do you wish the password? Minimum 8 maximum 1024: asdsads
Please enter a valid NUMBER...
好的，它会检测我是否输入了非数值，
现在让我们试试 8 以下的数字（最小值。
How many characters do you wish the password? Minimum 8 maximum 1024: 1
Minimun 8 characters - maximum 1024, try again
Generated password: $
How many characters do you wish the password? Minimum 8 maximum 1024: 3
Minimun 8 characters - maximum 1024, try again
Generated password: $?$)
好的，它会显示消息“最少 8 个字符 - 最多 1024 个字符，再试一次”，但它会计算密码
现在让我们试试最大值
How many characters do you wish the password? Minimum 8 maximum 1024: 1030
Minimun 8 characters - maximum 1024, try again

How many characters do you wish the password? Minimum 8 maximum 1024:
提示数字大于 1024 但再次计算密码
如果我确实计算了一个密码，比方说，10 个字符..没问题，如果我想计算另一个...20，它从之前的计算中提取前 10 个，然后加上 10更多填充 20（也许我必须清除或删除变量）

你走在正确的轨道上。当我们重新启动 while 循环时，您只是忘记了重置密码。而且在打印最小和最大长度的错误后你也没有继续。但是当它被修复时，它就起作用了：
from random import randint
lowerCase = "abcdefghijklmnopqrstuvwxyz"
upperCase = lowerCase.upper()
numbers = "1234567890"
special = "!#$%&/()=?¡@[]_<>,."
password_creation = lowerCase + upperCase + numbers + special
while True:
# pulled password and length in here to reset on each loop
password = ""
length = 0
try:
password_length = int(input("How many characters do you wish the password? Minimum 8 maximum 1024: "))
if password_length < 8 or password_length > 1024:
print("Minimun 8 characters - maximum 1024, try again")
# add continue, to not try to create password, if validation fails
continue
except ValueError:
print("Please enter a valid NUMBER...")
continue
else:
while length < password_length:
password = password + password_creation[randint(0, len(password_creation) - 1)]
length += 1
print("Generated password: ", password)
我还将 lenght 和 password_lenght 重命名为 length 和 password_length，所以如果你在其他地方使用它们，请注意这一点
我能够修复它
如果输入非数字字符，它会验证用户输入以捕获错误
它检查输入的值是否在范围内
它计算密码
完成后退出
这里是代码，我花了一整天但是...我能够
from random import randint
lowerCase = "abcdefghijklmnopqrstuvwxyz"
upperCase = lowerCase.upper()
numbers = "1234567890"
special = "!#$%&/()=?¡@[]_<>,."
mega_pass = lowerCase+ upperCase + numbers + special
lenght = 0
password_lenght = 0
password = ""
while True:
try:
password_lenght = int(input("How many characters long do you want the password? (min 8 - max 100; \n"))
except ValueError:
print("\nNumbers please...")
if password_lenght not in range (8, 101):
print("\nEnter a digit between 8 and 100...")

while lenght < password_lenght:
