建立視窗

from tkinter import *

root = Tk()
myLabel = Label(root, text="This is my text")
myLabel.pack() # pack()->由上而下、由左而右  grid()->指定索引位置  place()->絕對位置

root.mainloop()  # 不斷循環

更改大小

import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=300, height=300)
canvas.pack()

root.mainloop()

建立點擊後可跳出資訊的畫面

import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=500, height=500)
canvas.pack()  

def hello():
    label = tk.Label(root, text="Hello World!!", fg='green',
                     font=('helvetica', 12, 'bold'))
    # foreground -> 前景顏色
    canvas.create_window(250, 300, window=label)

button = tk.Button(text="Click Me!!", fg='black', comman=hello)
canvas.create_window(250, 250, window=button)
root.mainloop()

from flask import Flask

# create flask app
app = Flask(__name__)

@app.route("/")
def index():
    return "This is my homepage!!"

if __name__ == '__main__':
    app.run(debug=True)

加入html，做為顯示網頁資訊
