我正在尝试在Python中创建一个必须包含大写字母,小写字母和数字的密码生成器,并且长度必须介于6到20个字符之间。
import random
import string
def password_gen():
while True:
length = random.randint(6,20)
pwd = []
for i in range(length):
prob = random.random()
if prob < 0.34:
char = random.choice(string.ascii_lowercase)
pwd.append(char)
elif prob < 0.67:
char = random.choice(string.ascii_uppercase)
pwd.append(char)
else:
char = str(random.randint(0,9))
pwd.append(char)
pwd = ''.join(pwd)
#check password here
return pwd
但是,我无法检查密码以确保其中包含前面列出的所需字符。我不确定是否/如何使用继续声明。非常感谢任何帮助!

我认为如果您只是提前处理这些要求,这将更容易确保您满足基本要求。
import random
import string
def generate_pw():
length = random.randint(6,20) - 3
pwd = []
pwd.append(random.choice(string.ascii_lowercase))
pwd.append(random.choice(string.ascii_uppercase))
pwd.append(str(random.randint(0,9)))
# fill out the rest of the characters
# using whatever algorithm you want
# for the next "length" characters
random.shuffle(pwd)
return ''.join(pwd)
这将确保您的密码包含您需要的字符。对于其他字符,您可以使用所有字母数字字符列表并调用random.choice
length
次。

您可以使用isupper()和islower()函数来获取密码是否包含大写和小写。
e.g。
upper=0
lower=0
for i in range(length):
if (pwd[i].islower()):
upper=1
elif (pwd[i].isupper()):
lower=1

import random
import string
def password_gen():
lower_case_letter = random.choice(string.ascii_lowercase)
upper_case_letter = random.choice(string.ascii_uppercase)
number = random.choice(string.digits)
other_characters = [
random.choice(string.ascii_letters + string.digits)
for index in range(random.randint(3, 17))
]
all_together = [lower_case_letter, upper_case_letter] + other_characters
random.shuffle(all_together)
return ''.join(all_together)

密码生成器更细分,你可以得到任何你想要的数字,但它输出一个模式,先添加字母,然后是数字,最后是符号
import random
letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']
numbers = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
symbols = ['!', '#', '$', '%', '&', '(', ')', '*', '+']
print("Welcome to the PyPassword Generator!")
nr_letters= int(input("How many letters would you like in your password?\n"))
nr_symbols = int(input(f"How many symbols would you like?\n"))
nr_numbers = int(input(f"How many numbers would you like?\n"))
passwordlength = nr_letters + nr_numbers + nr_symbols
chars = ""
for x in range (0, nr_letters):
char = random.choice(letters)
chars += char
nums = ""
for y in range (0, nr_numbers):
num = random.choice(numbers)
nums+=num
syms = "" # string accumulator
for z in range (0, nr_symbols):
symb = random.choice(symbols)
syms += symb
print(f"Here is your password: {chars}{nums}{syms}")

Uppercase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
Lowercase = "abcdefghijklmnopqrstuvwxyz"
Digits = "0123456789"
Symbols = "()!?*+=_-"
Mixedbag = Uppercase + Lowercase + Digits + Symbols
#This function allwos the user to generate a random password containing x
amount of uppercase, lowercase and symbols to form a password
def generate():
print ("Starting the word generating process")
time.sleep(1)
while True:

Madeword = ""
for x in range(word_length):

Madeword = Madeword + ch
