如何使用 selenium python send_keys 将表格 dataframe 发送到网页的文本区域？

Question

So i'm able to print the tabulated dataframe in my console and now i want to send the same tabulated dataframe in an text area of webpage. Below is my code where excel_data_df1 read the excel file as pandas, and i'm using python 3.8. Attached the screenshots for reference.

SelectUp = excel_data_df1[(excel_data_df1['Marketplace'] == 'US') & (excel_data_df1['Product Line'] == 'Books')]
Guideline = print(tabulate(SelectUp, headers='keys', tablefmt='psql',showindex=False))
driver.find_element_by_id('tab_work_log').click()
WL = driver.find_element_by_id('work_log')
WL.send_keys(Guideline)

Tabulated dataframe in console screenshot Error screenshot

Answer 1

AFAIK print() method doesn't return actual value ie it returns nothing.
This actually causes Guideline to become None type object.
That's why

WL.send_keys(Guideline)

actually

WL.send_keys(None)

throws that error
