带熊猫的python：文件大小（44546）不是512 +扇区大小（512）的倍数

Question

用熊猫读取excel文件后，收到以下警告：

键码：

pd_obj = pd.read_excel("flie.xls", dtype=str, usecols=usecols, skiprows=3)

for idx, row in pd_obj.iterrows():    
    json_tmpl = copy.deepcopy(self.details)
    json_tmpl["nameInBank"] = row["nameInBank"]
    json_tmpl["totalBala"] = row["totalBala"].replace(",", '')
    # parse pdf file
    status = self._get_banksplip_json(json_tmpl["bankReceipts"], row)
    json_buf.append(copy.deepcopy(json_tmpl))

警告信息：

WARNING *** file size (48130) not 512 + multiple of sector size (512)
WARNING *** file size (44546) not 512 + multiple of sector size (512)

这似乎是来自底层XLRD库的正常警告，并且可以忽略。熊猫问题（#16620）已打开并关闭，而没有最终决议。但是，讨论确实提供了一种替代方法，使您可以禁止显示警告：

from os import devnull
import pandas as pd
import xlrd

wb = xlrd.open_workbook('file.xls', logfile=open(devnull, 'w'))
pd_obj = pd.read_excel(wb, dtype=str, usecols=usecols, skiprows=3, engine='xlrd')
