【问题描述】：

我想在 GUI 中以不同的行显示数组的数据。这是代码。

import tkinter as tk
window = tk.Tk()
window.configure(background='white')

ws = window.winfo_screenwidth()
hs = window.winfo_screenheight()
w = 200  # width for the Tk root
h = 500  # height for the Tk root
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)



window.geometry('%dx%d+%d+%d' % (w, h, x, y))
canvas = tk.Canvas(window, bg="white", width=980, height=580, highlightthickness=0)
canvas.pack()
canvas_scroll = tk.Scrollbar(canvas, command=canvas.yview)
canvas_scroll.place(relx=1, rely=0, relheight=1, anchor=tk.NE)
canvas.configure(yscrollcommand=canvas_scroll.set, scrollregion=())


op = ("Hello", "Good Morning", "Good Evening", "Good Night", "Bye")

l9 = tk.Label(canvas, text=op, font= "calibri 13", bg="white")
canvas.create_window(33,33, window=l9, anchor=tk.NW)  



window.mainloop()

我想要这样的输出：

你好

早安

晚上好

晚安

再见

你也可以试试这个：

op = ("Hello", "Good Morning", "Good Evening", "Good Night", "Bye")

def applytoLabel():
    n = len(op)
    element = ''
    for i in range(n):
        element = element + op[i]+'\n' 
    return element

l9 = tk.Label(canvas, text=applytoLabel(), font= "calibri 13", bg="white")
canvas.create_window(33,33, window=l9, anchor=tk.NW)

输出：

完整代码：

import tkinter as tk
window = tk.Tk()
window.configure(background='white')

ws = window.winfo_screenwidth()
hs = window.winfo_screenheight()
w = 200  # width for the Tk root
h = 500  # height for the Tk root
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)



window.geometry('%dx%d+%d+%d' % (w, h, x, y))
canvas = tk.Canvas(window, bg="white", width=980, height=580, highlightthickness=0)
canvas.pack()
canvas_scroll = tk.Scrollbar(canvas, command=canvas.yview)
canvas_scroll.place(relx=1, rely=0, relheight=1, anchor=tk.NE)
canvas.configure(yscrollcommand=canvas_scroll.set, scrollregion=())


op = ("Hello", "Good Morning", "Good Evening", "Good Night", "Bye")

def applytoLabel():
    n = len(op)
    element = ''
    for i in range(n):
        element = element + op[i]+'\n' 
    return element

l9 = tk.Label(canvas, text=applytoLabel(), font= "calibri 13", bg="white")
canvas.create_window(33,33, window=l9, anchor=tk.NW) 

window.mainloop()
