Question

所以我有这个pandas数据表，我希望写入excel工作簿。我正在使用pyexcelerate包。这是我的代码：

from pyexcelerate import Workbook

def df_to_excel(df, path, sheet_name='Sheet 1'):
    data = [df.columns.tolist(), ] + df.values.tolist()
    wb = Workbook()
    wb.new_sheet(sheet_name, data=data)
    wb.save(path)

df_to_excel(df=MergedDataAll, path=merged_file)

在我使用相同代码之前，我没有遇到此问题;但今天这个错误不断出现：

    df_to_excel(df=MergedDataAll, path=merged_file)

我尝试使用谷歌搜索，并使用类似于
