测试环境

Python 3.13.1
tkinter 8.6.15
Pillow 11.0.0

logo 为外部图片文件

通过文件的方式设置图标，在打包程序的时候注意把图片和程序一起带走，不然运行的时候找不到

ico

tkinter 可以直接使用 ico 文件，指定文件路径就行。

import tkinter

class Application(tkinter.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()

    def hello(self):
        self.label = tkinter.Label(self, text="Hello World!")
        self.label.pack()

def main():
    root = tkinter.Tk()
    root.title("你好，世界")
    root.geometry("400x20+300+200")

    # ico 文件
    logoPath = 'favicon.ico'
    root.iconbitmap(logoPath)

    app = Application(master=root)
    app.hello()
    app.mainloop()

if __name__ == '__main__':
    main()

任意图片文件

要支持任意图片文件就需要使用 Pillow 来打开图片

import tkinter
from PIL import ImageTk

class Application(tkinter.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()

    def hello(self):
        self.label = tkinter.Label(self, text="Hello World!")
        self.label.pack()

def main():
    root = tkinter.Tk()
    root.title("你好，世界")
    root.geometry("400x20+300+200")

    # 图片文件
    logoPath = 'favicon.png'
    logo = ImageTk.PhotoImage(file=logoPath)
    root.iconphoto(False, logo)

    app = Application(master=root)
    app.hello()
    app.mainloop()

if __name__ == '__main__':
    main()

logo 内置于代码中

logo 为外部图片文件的时候，如果缺失了图片文件可能就会导致程序执行异常，需要将图片文件和代码一起打包，将图片文件内置于代码中就不需要额外处理图片路径。
在线图片转 base64：https://iyatt.com/tools/img2base64/
将需要用作 logo 的图片转为 base64 字符串，如果图片分辨率比较大，建议先缩放一下，不然字符串非常的长。比如可以用画图，这里把图片转为 38×50 大小

import tkinter
from PIL import ImageTk, Image
import base64
from io import BytesIO
import re

class Application(tkinter.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()

    def hello(self):
        self.label = tkinter.Label(self, text="Hello World!")
        self.label.pack()

def main():
    root = tkinter.Tk()
    root.title("你好，世界")
    root.geometry("400x20+300+200")

    # 图片 base64 字符串
