從別的地方的呼叫 output_to_console 函數，裏面的 global console 竟然不是同一個，真是神奇了。 解決方法: python — 怎麼在兩個檔案之間分享全域變數 main.py import tkinter as tk import threading # 初始化全域變數 console = None console_initialized = threading . Event() # 用於等待 console 初始化完成 def set_console (widget): global console console = widget console_initialized . set() # 設置 console 已初始化完成 def output_to_console (text): global console print (f "output_to_console: id(console) = {id(console)}" ) # 打印 console 的 id 來檢查是否相同 if console is not None : console . insert(tk . END, text + " \n " ) console . see(tk . END) # 自動滾動到最底部 else : print ( "console 未初始化，無法輸出訊息" ) def create_window (): global console root = tk . Tk() root . title( "Console Example" ) set_console(tk . Text(root, wrap = tk . WORD, width = 50 , height = 20 , bg = "light yellow" , bd = 3 , relief = "solid" )) console ....

這個程式碼是透過 Copilot 產生出來的，一開始都無法成功，中間還有時候給出上次完全一樣的錯誤程式碼，沒有仔細看還會被騙過，搞了快一小時總會產生可用的程式碼。 這個功能只是在 main.py 產生一個類似 console 的視窗，按了按鈕後執行其它 py 檔的函數，然後可以把資料輸出到 console 視窗。自己寫一直出現錯誤，也找不到為什麼，只好借助AI來幫忙。 main.py import tkinter as tk import config # 確保匯入 config 模組 def create_window (): root = tk . Tk() root . title( "Console Example" ) config . set_console(tk . Text(root, wrap = tk . WORD, width = 50 , height = 20 , bg = "light yellow" , bd = 3 , relief = "solid" )) config . console . pack(pady = 10 ) from external_script import external_function # 在 console 初始化完成後匯入 # 添加一個按鈕來呼叫 external_function test_button = tk . Button(root, text = "呼叫外部函數" , command = external_function) test_button . pack(pady = 10 ) root . after( 1000 , lambda : config . output_to_console( "這是一條測試訊息" )) root . mainloop() if __name__ == "__main__" : create_window() external_script.py from config im...

create a=[] 新增一個空序列。 a=[1]*3=[1,1,1] 新增一個序列，裏面放了3個1。 a=[1 for i in range(3)]=[1,1,1] 新增一個序列，裏面放了3個1。 ';'.join(a) 將序列 a 產生一個字串 '1;1;1'。 Reference Python List必學實作 序列类型 --- list, tuple, range Python 推导式 P ython String join()
