我正在創(chuàng)建一個密碼生成器，它獲取所需密碼的長度、字母數(shù)量以及數(shù)字數(shù)量。密碼需要包含大寫字母以及數(shù)字和特殊字符。我無法弄清楚如何指定密碼中的字母和數(shù)字的數(shù)量。這是我到目前為止所擁有的：import randomcharslet ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"charsnum = "1234567890"charssym = "!@#$%^&*"def password(): pwd = "" passlen = int(input("How long do you want the password to be?: ")) passlet = int(input("How many letters do you want in your password?: ")) passnum = int(input("How many numbers do you want in your password?: ")) passsym = int(passlen - (passlet + passnum)) chars = "" for let in range(passlet): chars += random.choice(charslet) for num in range(passnum): chars += random.choice(charsnum) for sym in range(passsym): chars += random.choice(charssym) for p in range(passlen): pwd += random.choice(chars) print(pwd)password()

我認為最后一部分讓你感到困惑。您正在使用chars正確數(shù)量的特定字符構建變量，但最后您再次在它們之間進行選擇。
你可以改變：
for p in range(passlen):
password += random.choice(chars)
和
# option 1 - works better if working with lists
list_chars = list(chars)
random.shuffle(chars)
password = "".join(list_chars)
# option 2 - simpler solution for strings
password = "".join(random.sample(char, len(char)))
您還可以使用 shuffle 來選擇之前的字符，而不使用 for 循環(huán)，例如：
# for this to work your `charslet` must be a list
random.shuffle(charslet)
chars += "".join(charslet[:passlet])

這是更正后的代碼：
import random
charslet ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
charsnum = "1234567890"
charssym = "!@#$%^&*"
def password():
pwd = ""
passlen = int(input("How long do you want the password to be?: "))
passlet = int(input("How many letters do you want in your password?: "))
passnum = int(input("How many numbers do you want in your password?: "))
passsym = int(passlen - (passlet + passnum))
chars = ""
for let in range(passlet):
chars += random.choice(charslet)
for num in range(passnum):
chars += random.choice(charsnum)
for sym in range(passsym):
chars += random.choice(charssym)
list_chars = list(chars)
random.shuffle(list_chars)
pwd = "".join(list_chars)
print(pwd)
password()
我替換：
for p in range(passlen):
password += random.choice(chars)
和
list_chars = list(chars)
random.shuffle(list_chars)
pwd = "".join(list_chars)
將更改后的chars變量放入列表中可以讓我對其進行洗牌、隨機化并允許我將其分配給pwd
