嘗試將熊貓數據框保存到現有Excel工作表時出現AttributeError

Question

我正在嘗試將熊貓數據框寫入新選項卡上的現有excel工作表，但是它給了我以下錯誤：

AttributeError：“ NoneType”對象沒有屬性“ read”。

我確定這是因為熊貓to_excel返回了NoneType對象，這不允許我使用writer.save（）保存文件。 有誰知道解決方法？

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()

Answer 1

我有完全一樣的問題。 我設法通過從工作簿的每個工作表中刪除legacy_drawing中的值來解決此問題。

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()
