Python Script with widgets

[prettel1]

Hello, I am pretty new on power Bi and Python, I am trying to use a scrip to read around 300 excel files and append or concat them but once those file have been appended, 99% of the time I wont need to read them again so just in case I did a scrip with a check box that let me decide if I want or not to read again all historical data, It works on anaconda notebook but when I try to run it in Power BI I got 

Details: "ADO.NET: Python script error.
<pi>NameError: name 'display' is not defined
</pi>"  

The Script :

import ipywidgets as widgets
import os
import pandas as pd

import glob 

path_data=r'C:\Users\xxxxx\Desktop\All'

check=widgets.Checkbox(value=False,
description='Refresh Historic Data',
disabled=False,
indent=False)
display(check)

if check.value ==False:
path_data=r'C:\Users\m0188842\Desktop\All\1'
elif check.value ==True:
path_data=r'C:\Users\m0188842\Desktop\All'

os.chdir(path_data) 

filenames = glob.glob('*.xlsm*') 

df_final = pd.DataFrame() 
for file in filenames: 

df = pd.read_excel(file, sheet_name='Consolidation') 
df_final=pd.concat([df,df_final],ignore_index=True)

df_final.to_csv(os.path.join(path_data, 'Test1.csv'), index=False)

The question is Can I sue widgets on Power Bi?

Thank you!

You can only use the default renderer. No other renderers are permitted.

If you run this in Power Query then there is no renderer at all.  Comment out that line.  You cannot have any UI during the Power Query part.
