Python script in Power BI transform data/power query returns date as Microsoft.OleDb.Date

Hi, guys.

I am having issues when I use python script in transforming data. The date became unreadable? or Microsoft.OleDb.Date. May I know the most effective way to fix it? Here's my python script:

import pandas as pd

dataset = pd.DataFrame(data=data)

dataset['Supplier Name'] = dataset['Name'].str.replace(r'^.*-\s*', '').str.strip()

dataset.drop(columns=['Name'], inplace=True)

dataset.reset_index(drop=True, inplace=True)
