熊猫日期时间1列/难以拆分

Question

抱歉，这似乎是一个愚蠢的问题，但我正在努力将一个“约会时间”列拆分为（a：日期，b：时间）

CSV文件表

    Description     Qty Amount  Date Time
0   Card Payment    1   9.60    2017-01-02 18:05:02
1   Card Payment    1   4.49    2017-01-02 17:59:43
2   Card Payment    1   8.55    2017-01-02 17:34:55
3   Card Payment    1   15.00   2017-01-02 17:16:36
4   Card Payment    1   25.92   2017-01-02 17:15:01    

代码

import pandas as pd
df = pd.read_csv("Card20170102.csv", skiprows=range(0, 2))
print (df.dtypes)
df['Date Time'] = pd.to_datetime(df['Date Time'])
print (df.dtypes)
df.head()

列格式

Description     object
Qty              int64
Amount         float64
Date Time       object
dtype: object

Description            object
