从一天中删除小时、分钟和秒，Python

Question

taxa_bruta_cdi = pd.read_csv("dados CDI .csv",delimiter=";",encoding='cp1252')

taxa_cdi= pd.DataFrame(taxa_bruta_cdi,columns=["Data","Media"])

taxa_cdi['Data'] = pd.to_datetime(taxa_cdi['Data']).dt.normalize()

taxa_cdi=taxa_cdi.pivot_table(index="Data",values="Media",aggfunc='sum')

taxa_cdi.sort_index(axis=0, level=None, ascending=True, inplace=False, kind='quicksort', na_position='last', sort_remaining=True, by=None)    

我想从日期中删除小时、分钟和秒。

Answer 1

尝试这个：

taxa_cdi['Data'] = taxa_cdi['Data'].dt.strftime('%Y-%m-%d')
