如何在 python 的系列中逐月交换？

Question

I have a column in which there are dates:

df['Date']

    Date
0 2020-25-04
1 2020-26-04
2 2020-27-04
3 2020-12-05
4 2020-06-05
Name: Date, Length: 5, dtype: datetime64[ns]

I want to swap the element Day by element Month, so I can have:

df['Date']

     Date
0 2020-04-25
1 2020-04-26
2 2020-04-27
3 2020-05-12
4 2020-05-06
Name: Date, Length: 5, dtype: datetime64[ns]

Any help would be appreciated.

Answer 1

import pandas as pd
import numpy as np

df = pd.DataFrame({'Date':[np.datetime64('2020-04-25') ,np.datetime64('2020-04-26')]})

df['Date'] = df['Date'].apply(lambda x: x.strftime('%Y-%m-%d'))

print(df)

I converted data into np.datetime format and applied lambda function.
