I am struggling to convert a object type to datetime. It's a column from a dataframe which has time values in format hh:mm:ss.
dataframe: df_train column: time values in format: hh:mm:ss
Below are the options which I already tried without any luck
Opt1:
df_train['time'] = pd.to_datetime(df_train['time'])
Error:
TypeError: <class 'datetime.time'> is not convertible to datetime
Opt2:
df_train['time'] = pd.to_datetime(df_train['time'], format='%H:%M:%S').dt.time
Outcome:
The code is working but the type remain as object.
Opt3:
df_train['time'] = pd.to_datetime(df_train['time'].str.strip(), format='%H:%M:%S')
Outcome:
value changed to NaT
Opt4:
df_train['time'] = pd.to_datetime(df_train['time']).dt.time
Error:
TypeError: <class 'datetime.time'> is not convertible to datetime
Appreciate your suggestions to convert this column to type datetime.
Just try this :
dat['column'] = pd.to_datetime(dat['column'])
OR pd.read_csv(file, parse_dates=['column'])
when reading data from file
我想很近,您需要的是to_timedelta
for timedeltas,并将python对象时间转换为字符串:
df_train['time'] = pd.to_timedelta(df_train['time'].astype(str))
