我想知道如何获得6个唯一的随机数。我已经读过random.sample,但就我而言,我正在生成5个数字1-69和第6个数字1-26。我需要所有6个都是唯一的。这是我的代码。

import tkinter
import random

class Lottery_GUI:
    def __init__(self):
        self.main_window = tkinter.Tk()
        self.main_window.geometry('500x100')
        self.main_window.title('Lottery Number Generator')
        self.frame1 = tkinter.Frame(self.main_window)
        self.frame2 = tkinter.Frame(self.main_window)

        self.frame1.pack()
        self.frame2.pack()

        self.list1 = tkinter.IntVar()

        #Lottery label
        self.Lottery_label = tkinter.Label(self.frame1,\
                        text = 'Welcome to the Lottery Generator')

        self.Lottery_label.pack()

        #Button to generate the numbers
        self.Lottery_button = tkinter.Button(self.frame2,\
                        text = 'Click to Generate Numbers',\
                        command = self.Generate_Num)

        self.Lottery_button.pack()

        #Display the random numbers

        self.num_entry = tkinter.Entry(self.frame1, textvariable = self.list1,\
                    width = 20, fg = 'blue', justify = 'center')

        self.num_entry.pack(side = 'bottom')

        tkinter.mainloop()

    def Generate_Num(self):
        a = random.randint(1,69)

        b = random.randint(1,69)

        c = random.randint(1,69)

        d = random.randint(1,69)

        e = random.randint(1,69)

        f = random.randint(1,26)

        list = [a,b,c,d,e,f]
        list.sort()
        self.list1.set(list)

my_lottery = Lottery_GUI()

我尝试在函数random.sample(range(1,70, 5)中进行Generate_Num,但是问题是我无法检查第6个仅在1-26之间的数字。

您可以取样而无需更换。参见np.random.choice

这应该有效:

a = np.random.choice(26, 1)
np.random.choice(np.delete(np.arange(69), a),5, replace=False)

a是您的第六个要素。

答案 1 :(得分:2)

使用randintsample进行过滤,而不使用choice

import random

first_five = random.sample(range(70), 5)
last = random.choice([number for number in range(27) if number not in first_five])

numbers = first_five + [last]
print(numbers)

输出:

[53, 52, 9, 0, 8, 21]

稍后您可以执行排序和其他操作。

此外,避免命名变量list,因为它会遮盖(隐藏)内置函数。
