'Series' object has no attribute 'to_datetime'
提问by wen
I am trying to convert one column str type to datetime type. But when I write the code:
我正在尝试将一列 str 类型转换为日期时间类型。但是当我写代码时：
df.timeStamp = df.timeStamp.to_datetime
it just tell me
它只是告诉我
AttributeError: 'Series' object has no attribute 'to_datetime'
But when I try
但是当我尝试
pd.to_datetime(df.timeStamp)
it works.
有用。
I am new to python and hope someone could explain why it happens.

Because to_datetimeis only a valid attribute to pandasmodule, that's all.
因为to_datetime只是pandas模块的有效属性，仅此而已。
So that's why:
所以这就是为什么：
AttributeError: 'Series' object has no attribute 'to_datetime'
AttributeError: 'Series' object has no attribute 'to_datetime'
(see highlighted part)
（见高亮部分）
So of course, to_datetimecan't be used that way.
所以当然to_datetime不能这样使用。

Below code converts a column of type objectin a pandas df to type timestamp
下面的代码将Pandas df中类型为object的列转换为类型时间戳
df.timeStamp = pd.to_datetime(df.timeStamp)
