I have a column with dates in string format \'2017-01-01\'. Is there a way to extract day and month from it using pandas?

I have converted the column to

Answer 1

With dt.day and dt.month --- Series.dt

df = pd.DataFrame({'date':pd.date_range(start='2017-01-01',periods=5)})
df.date.dt.month
Out[164]: 
0    1
1    1
2    1
3    1
4    1
Name: date, dtype: int64

df.date.dt.day
Out[165]: 
0    1
1    2
2    3
3    4
4    5
Name: date, dtype: int64

Also can do with dt.strftime

df.date.dt.strftime('%m')
Out[166]: 
0    01
1    01
2    01
3    01
4    01
Name: date, dtype: object
