如何打印在读取熊猫数据框中显示警告的文档名称

Question

在将excel文档读取到数据框期间，我收到此警告：

*

Warning (from warnings module):
  File "C:\Users\Slobo\AppData\Local\Programs\Python\Python37\lib\site-packages\pandas\core\frame.py", line 6211
    sort=sort)
FutureWarning: Sorting because non-concatenation axis is not aligned. A future version
of pandas will change to not sort by default.
To accept the future behavior, pass 'sort=False'.
To retain the current behavior and silence the warning, pass 'sort=True'.

*

要从特定文件夹中读取所有文档，请使用以下方法：

`for f in glob.glob(dirname + "/*.xlsx")`:
    #where dirname is the path to the folder, and then for reading documents:
    pd.read_excel(f)

我要打印在读取数据框时会引起警告出现的文档名称。

该怎么做？

Answer 1

import warnings
warnings.filterwarnings("error")

for f in glob.glob(dirname + "/*.xlsx"):
    try:
       pd.read_excel(f)
    except Warning as w:
        print(f)
