python - python itertools不打印10的倍数

Question

在我当前显示所有可能组合的 python 程序中，它没有显示 10 的倍数（10、20、30、40 等），我不明白为什么，我正在使用 itertools 库不知道是否有什么东西可以做到这一点？我在网上查了一下，没有找到类似的东西，所以也许它与我的安装有关？无论如何，这是代码。

import itertools
from pynput.keyboard import Controller
import time
keyboard = Controller()
loop = True
a = 1
input("Welcome to the Password Possibilities Test")
input("This test will tell you how many possible")
input("combinations a password can have")
input("*all answers must start with an uppercase*")
num_length = 0
alpha_length = 0
sym_length = 0
num = input("So lets start does your password have numbers?\n")
alpha = input("Does it have letters?\n")
sym = input("Does it have symbols?\n")
long = input("Do you know how long the password is?\n")

possibilities = []

if long == "Yes":
    length = input("How long is the password?\n")
elif long == "No":
    print("Then we will go off of the average password length which is 8\n")
    length = 8

if num == "Yes":
    num_length = 10
    possibilities.append(0)
    possibilities.append(1)

当您想显示所有可能的组合时，您的意思是关于重复排列的数学概念。在 itertools 库中的 python 中，只有排列，就像在数学中没有重复的排列一样。在 python 中，您可以使用 itertools.product 来换取它。我附在下面的完整功能代码：

import itertools
from pynput.keyboard import Controller
import time

keyboard = Controller()
loop = True
a = 1
input("Welcome to the Password Possibilities Test")
input("This test will tell you how many possible")
input("combinations a password can have")
input("*all answers must start with an uppercase*")
num_length = 0
alpha_length = 0
sym_length = 0
num = input("So lets start does your password have numbers?\n")
alpha = input("Does it have letters?\n")
sym = input("Does it have symbols?\n")
long = input("Do you know how long the password is?\n")

possibilities = []

if long == "Yes":
    length = input("How long is the password?\n")
elif long == "No":
    print("Then we will go off of the average password length which is 8\n")
    length = 8

if num == "Yes":
    num_length = 10
    possibilities.append("0")
    possibilities.append("1")
    possibilities.append("2")
    possibilities.append("3")
    possibilities.append("4")
    possibilities.append("5")
    possibilities.append("6")
    possibilities.append("7")
    possibilities.append("8")
    possibilities.append("9")

else:
    num_length = 0

if alpha == "Yes":
    alpha_length = 52
    possibilities.append("a")
    possibilities.append("b")
    possibilities.append("c")
    possibilities.append("d")
    possibilities.append("e")
    possibilities.append("f")
    possibilities.append("g")
    possibilities.append("h")
    possibilities.append("i")
