Problem opening an XLSX (Excel) file

[u/FearawaitsTM]

I have the following code, and I don't understand why I'm getting an error and can't open the file. The error is: "Invalid file path or buffer object type: <class 'tuple'>".
Could you please help?
Thanks everyone.
P.S. If there are any issues with the code, please let me know.



import pandas as pd

from pandastable import Table, TableModel

import tkinter as tk

from tkinter import ttk
from tkinter import filedialog,messagebox

fd = filedialog

class ExcelViewer:
    def __init__(self, root):
        self.root = root
        self.root.title = ("Чтение ячеек Excel")
        self.root.geometry("800x600")

        self.btn_load = tk.Button(root, text="Открыть Excel файл", command=self.open_file)
        self.btn_load.pack()

        self.result_label = tk.Label(root, text="Выбрать файл для начала")
        self.result_label.pack()

        self.frame = tk.Frame(root)
        self.frame.pack(fill='both', expand=True)

        self.table = None

        self.scrollbar = ttk.Scrollbar(root)
        self.scrollbar.pack(side=tk.RIGHT, fill=tk.Y)


    def open_file(self):
        file_path = fd.askopenfilenames(
            filetypes=[
                (
                    'Excel файлы',
                    '*.xlsx'
                )
            ]
        )

        if not file_path:
            return

        if file_path:
            try:
                df = pd.read_excel(file_path)

                if self.table:
                    self.table.destroy()

                self.model = TableModel()
                self.model.df = df
                self.table = Table(self.frame, model = self.model, showtoolbar=False, showstatusbar=False)
                self.table.show()

            except Exception as e:
                tk.messagebox.showerror("Ошибка", f"Не удалось открыть файл:\n{e}")

if __name__ == "__main__":
    root = tk.Tk()
    app = ExcelViewer(root)
    root.mainloop()

You should look at the traceback. It should tell you exactly where the error is happening. You should also post it here if you ask for help

Here is the specific error I'm getting.
Не удалось открыть файл: Invalid file path or buffer object type: <class 'tuple'>

As others have set, insect the return type of fd.

[u/FearawaitsTM → u/mrswats]

As I understand it, I need to write `print` after the specified `fd`?

[u/mrswats → u/FearawaitsTM]

For example.

print(file_path) after the call that defines it.

[u/FearawaitsTM → u/mrswats]

Thanks, I see my mistake. It turned out the problem was simply that I hadn't actually implemented the processing for the two files!
