How can I make that in label generate some numbers for example:
some text(e.g.Input): #here generate numbers#
Input and Output are text in label I want to make that number are generated every second in the label
要在每个随机数之间等待一秒钟,请使用该after
方法并更改预定函数中的文本:
from tkinter import Tk, Label
import random
root = Tk()
label = Label(root)
label.pack()
def replace_text():
label.config(text=str(random.random()))
root.after(1000, replace_text)
replace_text()
root.mainloop()
这是你要找的吗?每按一次按钮,就会显示一个新的随机数。
import tkinter as tk
import random
class Window:
def __init__(self, master):
self.frame = tk.Frame(master)
self.text = tk.StringVar()
self.text.set(random.randint(1, 10))
self.ranNumLabel = tk.Label(self.frame, textvariable = self.text)
self.genButton = tk.Button(self.frame, text = 'Generate Random Number', command = self.genRanNum)
self.ranNumLabel.grid(row = 0)
self.genButton.grid(row = 1)
self.frame.grid()
def genRanNum(self):
self.text.set(random.randint(1, 10))
# when text is updated, the Label associated with it also updated
def main():
root = tk.Tk(className = ' Random Number Generator')
app = Window(root)
root.mainloop()
if __name__ == '__main__':
main()
您的问题相当令人困惑,但这是我可以回答的...要生成随机数,请使用random.random()
函数和label()
tkinter 中的函数。
这是一个例子:
import random
from tkinter import *
x=random.random()
root = Tk()
w = Label(root, text=x)
w.pack()
root.mainloop()
