如何在 excel 中查找数据并在其旁边返回值？

Question

My Excel data:

Excel data

What Im I doing?

I have been looking into pandas , openpyxl all sorts of modules. Not sure how to assemble a script to do me a vlookup() function.

What I am trying to do is, give a variable of find_string = "John" and use it to look inside the sheet and return me Last Name connected on the same row as the First Name of John .

Example

find_string = "John"

return value of John = West

because John and West are on the same row but different column.

How can this be done?

This is what I got to..

import pandas as pd

file = 'C:/Users/user/Desktop/test/Excel file.xlsx'

find_string = "John"

x = pd.read_excel(file, sheet_name = 'Sheet2')

UPDATE FROM AN ANSWER Return value:

IMG

file = 'C:/Users/user/Desktop/test/Excel file.xlsx'
df = pd.read_excel(file, sheet_name = 'sheet2')
 new_df = df[df['First Name'].str.contains('John')][['Last Name']].reset_index(drop = True) 

I need to return just the word West

For this specific case, you can just use the pandas Series.str.contains(). The documentation is on this link https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.str.contains.html . For your specific example, something like this could suffice.

file = 'C:/Users/user/Desktop/test/Excel file.xlsx'
df = pd.read_excel(file, sheet_name = 'sheet2')
new_df = df[df['First Name'].str.contains('John')]
