如何将今天的日期放在 Python 数据框中每一行的第一列？

Question

I use the following code to move data from one Excel file to another:

import pandas as pd
inventory=pd.read_excel('Original_File.xlsx', skiprows=3)
inventory.to_excel('New_File.xlsx', index=False)

How do I place today's date in the first column of every row that contains data in New_File.xlsx?

Answer 1

Like this:

import pandas as pd
from datetime import datetime
inventory=pd.read_excel('Original_File.xlsx', skiprows=3)
inventory.insert(0, 'today_date', datetime.today().strftime('%Y-%m-%d'))
inventory.to_excel('New_File.xlsx', index=False)
