"Error: List index out of range" Over a list of 952 xlsx files, how edit and then save as csv

Question

目标是合并 952 个 excel 文件的 sheet1 和 sheet2 中的重要信息。然后根据单元格值将它们保存为路径中的 csvs 作为名称。感谢 Whosebug 社区，这主要是工作。现在，它给出错误：“列表索引超出范围”。这发生在中途点附近，特别是正确保存的 475 到 516 个文件。

有人能为整个列表做这个吗？

import glob
import pandas as pd

excel_files = glob.glob('data1/*.xlsx')
path = Path('data2')
for excel in excel_files:
    df1 = pd.read_excel(excel, sheet_name=0, dtype=str, index_col=None)
    df2 = pd.read_excel(excel, sheet_name=1, dtype=str, index_col=None)
    i = df1.iat[0,1]
    j = df1.iat[0,15]
    df2.rename(columns={'Date':'Date','Sales':i+j}, inplace=True)
    df2.columns=df2.columns.str.replace('(','') 
    df2.columns=df2.columns.str.replace('/','')
    df2.columns=df2.columns.str.replace(')','')
    df2.columns=df2.columns.str.replace(' ','-')
    df2.columns=df2.columns.str.replace('<','-')
    df2.columns=df2.columns.str.replace('>','-')
    k = df2.columns[1]
    l = (k)[:19]
    m = l + '.csv'
    df2.to_csv(path/m, encoding='utf-8', index=False)

->编辑如下： 根据要求进行堆栈跟踪。至少谢谢你看一看。

Chris's 解决了问题：

It means your particular excel workbook only has one sheet unlike the others and read_excel fails if parameter sheet_name is 1. If you want to handle that case, you need to wrap your pandas.read_excel call inside a try / except clause.
