Dataframe不输出到Excel

Question

我正在发布我的代码片段，以尝试调试。我正尝试将df4输出到Excel中，但输出中总是出现空白。我已经试着自己解决了几个小时的问题，但还是不能解决问题。

from bs4 import BeautifulSoup
import os
import glob
import pandas as pd

os.chdir('C:/Users/PCTR261010/Desktop/Attribute Convert')
FileList = glob.glob('*.txt')

for fname in FileList:
    soup = BeautifulSoup(open(fname), 'html.parser')

    data = soup.find('data').text

    for partno in data.split('\n'):
        df4 = pd.DataFrame([partno.split('\t')])

        sheet_name = ('MPCC@' + soup.find('leafname').text)
        writer = pd.ExcelWriter(os.path.join(fname + '.xlsx'), engine='xlsxwriter')
        df4.to_excel(writer, sheet_name=sheet_name, startrow=0, startcol=0, index=False, header=False)

        writer.save()

Answer 1

试试这个：

def f(fname):
    soup = BeautifulSoup(open(fname), 'html.parser')
    data = soup.find('data').text
    sheet_name = ('MPCC@' + soup.find('leafname').text)

    df = pd.read_csv(io.StringIO(data), sep='\t', header=None)
    df.to_excel((os.path.join(fname + '.xlsx'), sheet_name=sheet_name, index=False, header=False)

# process all files
for fname in FileList:
    f(fname)
