Question

我的数据框有一列日期，如2014-11-12。我想将其分为两列：年和 Month_date ，并将年份作为 2014年列入“年度”栏目＆＃39; 11月12日在＆lt; Month_date＆＃39;柱。 I have split Date column but not able to put in 'Nov 12' format。我是python的新手。任何帮助将受到高度赞赏。

我认为你需要：

df['Date'] =  pd.to_datetime(df['Date'])
df['Year'] = df['Date'].dt.year
df['Month-Date'] = df['Date'].dt.strftime('%m-%d')
print (df)
            ID       Date  Data_Value  Year Month-Date
0  USW00094889 2014-11-12          22  2014      11-12

df['Date'] =  pd.to_datetime(df['Date'])
df['Year'] = df['Date'].dt.year
df['Month-Date'] = df['Date'].dt.strftime('%b-%d')
print (df)
            ID       Date  Data_Value  Year Month-Date
