Event: I got angry when I tried to read an Excel file with Pandas

I made a code to read an Excel file with Python, made it an exe file with PyInstaller, changed the directory and executed it at the command prompt, and I got angry.

> my-code.exe

my-code.py

import pandas as pd

def check_files():
    #Read an Excel file
    book = pd.read_excel(excel_file, sheet_name=None, header=None)

Cause: There is a garbage file

There was a file that started with ~ $ that was created when I opened the Excel file ... Sometimes it remains even after closing the Excel file ... I couldn't see it in Explorer, but I could see it with the dir command ...

> dir data\
# ...abridgement...
2020/10/07  10:30               165 ~$Excel to be processed.xlsm

Action: Delete the garbage file

#Delete garbage files
> cd data\
> del "~$Excel to be processed.xlsm"

#It worked when there was no garbage
> cd ../
> my-code.exe
