How to modify date value to only keep month value

I have a df, you can have it by running:

import pandas as pd
from io import StringIO
    
df = """  
           case_id    scheduled_date        code
           1213       2021-08-17            1
           3444       2021-06-24            3
           4566       2021-07-20            5
          
    """
df= pd.read_csv(StringIO(df.strip()), sep='\s\s+', engine='python')

How can I change scheduled_date to only keep year and month? The output should be:

  case_id   scheduled_date  code
0   1213    2021-08         1
1   3444    2021-06         3
2   4566    2021-07         5

>Solution :

You can also try this:

df['scheduled_date'] = pd.to_datetime(df.scheduled_date, format='%Y-%m-%d').dt.strftime('%Y-%m')


   case_id scheduled_date  code
0     1213        2021-08     1
1     3444        2021-06     3
2     4566        2021-07     5
