如何在不指定excel名称的情况下从文件夹中读取excel？

Question

我想从文件夹read_excel并加载到数据库，但excel将每周刷新并更改名称（ReportWK01，ReportWK02，...）在该文件夹（名称To_Load）只是我需要的一个excel。

我尝试指定路径然后read_excel，但我不知道正确的语法。

path = rb'\\csd-file\dd\bb\ss\uu\To_Load'
results = os.path.join(path, rb"*\*.xlsx")
df = pd.read_excel(results, engine='python')

它是写我的

ValueError: Must explicitly set engine if not passing in buffer or path for io.

## can you try reading it based on most recent time stamp
import os                                                                   
import glob             

folder_path ='\\csd-file\dd\bb\ss\uu\To_Load'

# glob.glob returns all paths matching the pattern.
excel_files = list(glob.glob(os.path.join(folder_path, '*.xls*')))

mod_dates = [os.path.getmtime(f) for f in excel_files]
print(mod_dates)
# sort by mod_dates.
file_date = sorted(zip(excel_files, mod_dates),reverse=True)
print("*"*100)
print(file_date)
newest_file_path = file_date[0][0]
df = pd.read_excel(newest_file_path)
