我正在創建一個函式來獲取我的 gui 中的所有檔案，例如 vs 代碼。我嘗試了很多次，我創建了一個函式，通過它我可以在我的 gui 中獲取檔案夾檔案，但我無法從我的 gui 打開檔案，我也無法根據包含的擴展名將影像放在它們的名稱之前
錯誤：-

uj5u.com熱心網友回復：
您在串列框中打開選定的檔案夾而不是選定的檔案。您需要從串列框中獲取所選檔案并加入所選檔案夾以獲取完整檔案路徑：Open()
def Open(value):
# get the selected filename from listbox
file = list_box.get(list_box.curselection())
# get the absolute path of the selected filename
filepath = os.path.join(value, file)
editor.delete(1.0, END)
with open(filepath, "r") as f:
editor.insert(1.0, f.read())
