這是我的代碼：import pandas as pdimport numpy as npdata = {'ID': [1,2,3,4,5,6,7,8,9], 'Doc':['Order','Order','Inv','Order','Order','Shp','Order', 'Order','Inv'], 'Rep':[101,101,101,102,102,102,103,103,103]}df = pd.DataFrame(data)#df['concat']= (df['ID'].convert_dtypes(convert_string = True) + "1").convert_dtypes(convert_integer = True)df['concat']= (df['ID'].astype(str) + "1").convert_dtypes(convert_integer = True)print(df['concat'].dtype)輸出：string為什么不是以及如何獲得它？df['concat']Int64
