我正在尝试将熊猫数据框写入新选项卡上的现有excel工作表,但这会给我以下错误:
AttributeError:“ NoneType”对象没有属性“ read”。
我已经确定这是因为pandas to_excel返回了一个NoneType对象,这不允许我使用writer.save()保存文件。有人知道解决方法吗?
path = 'summary.xlsx'
book = load_workbook(path)
writer = pd.ExcelWriter(path, engine='openpyxl')
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
df.to_excel(writer, sheet_name="results")
writer.save()
答案 0 :(得分:0)
我有完全一样的问题。 我设法通过从工作簿的每个工作表中删除legacy_drawing中的值来解决此问题。
path = 'summary.xlsx'
book = load_workbook(path)
writer = pd.ExcelWriter(path, engine='openpyxl')
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
for s in list(writer.sheets.keys()):
writer.sheets[s].legacy_drawing = None
df.to_excel(writer, sheet_name="results")
writer.save()
