问题
In my script I have df['Time'] as shown below.
497 2017-08-06 11:00:00
548 2017-08-08 15:00:00
580 2017-08-10 04:00:00
646 2017-08-12 23:00:00
Name: Time, dtype: datetime64[ns]
But when i do
t1=pd.Timestamp(df['Time'][0])
I get an error like this :
KeyError: 0
Do I need any type conversion here, if yes then how it can be fixed?
回答1:
You're looking for df.iloc.
df['Time'].iloc[0]
df['Time'][0] would've worked if your series had an index beginning from 0
And if need scalar only use Series.iat:
df['Time'].iat[0]
