Question

所以我正在用python制作yahtzee游戏。单击按钮时，我将其设置为掷骰子。然后，您可以单击以防止再次滚动该数字。我的目标是将这个range（5）中的值分配给一个变量。最好我希望每次单击骰子按钮时都会更新该变量。

这只是为了我自己一直在努力使python变得更好的游戏。我尝试过想一种将其分配给字典的方法，但是我一直找不到方法。

from tkinter import *
from random import randint

root = Tk()
root.title("Sam's Yahtzee")

def roll(dice, times):
    if times > 0:
        dice['text'] = randint(1, 6)
        root.after(10, roll, dice, times-1)

def roll_dices():
    for i in range(5):
        if dices[i][1].get() == 0:
            # dice is not held, so roll it
            roll(dices[i][0], 10)

dices = []
for i in range(5):
    ivar = IntVar()
    dice = Checkbutton(root, text=randint(1, 6), variable=ivar, bg='silver', bd=1, font=('Arial', 24), indicatoron=False, height=3, width=5)
    dice.grid(row=0, column=i)
    dices.append([dice, ivar])

Button(text='Dice', command=roll_dices, height=2, font=(None, 16, 'bold')).grid(row=1, column=0, columnspan=5, sticky='ew')

yahtzee = 0
threeKind = 0
fourKind = 0
fullHouse = 0
smallStraight = 0
largeStraight = 0
chance = 0

possibleHands = {"yahtzee": yahtzee,
                 "threeKind": threeKind,
                 "fourKind": fourKind,
                 "fullHouse": fullHouse,
                 "smallStraight": smallStraight,
                 "largeStraight": largeStraight,
                 "chance": chance}

root.mainloop()

Answer 1

这是您想要的吗？

nums = list(range(5)) #nums is now list of [0,1,2,3,4]

Answer 2

除list(range(5))之外的另一种方式：

nums = [*range(5)]
print(nums)

# [0, 1, 2, 3, 4]

似乎也快了很多。（我使用100进行了更准确的测试。）

In [1]: %timeit nums = list(range(100))
3.24 µs ± 87.8 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [2]: %timeit nums = [*range(100)]
1.08 µs ± 40.2 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

Answer 3

我理解这一点，但是有办法让我获取相同的列表吗？ for循环中的数字？

我猜您只想执行一次语句块n（此处= 1000）次，并且每次使用相同的编号num。如果是这样，您可以使用：

n = 1000
num = 1 # the number you want to repeat
#Execute for 0.06280231475830078s
for i in [num]*n: 
    print(i)

或

n = 1000
num = 1 # the number you want to repeat
#Execute for 0.05784440040588379s
for _ in range(n):
    print(num)

如何将range（5）中的值分配给变量？
