Get the first word after specific word in a column

Question

I am trying to get the zip code after the specific word ‘zip_code’ within a string.

I have a data frame with a column named "location", in this column there is a string, I want to identify the word "zip_code" and get the value after this word for each row.

Input

name   location
 Bar1   LA Jefferson zip_code 202378 Avenue free
 Pizza  Avenue 45 zip_code 45623 wichita st
 Tacos   Las Americas avenue 7 zip_code 67890 nicolas st

Expected output

 name   location                                          
 Bar1    202378 
 Pizza   45623
 Tacos   67890

So far, following an example I was able to extract the zip code for any string

str = "address1 355 Turnpike Ste 4  address3 zip_code 02021 country    US   "
str.split("zip_code")[1].split()[0]
>> 02021

But I do not know how to do the same for each row of my column location

The best way is to use extract() which accepts regex and allows searching through each row.

import pandas as pd
import numpy as np

df = pd.DataFrame({'name':['Bar1', 'Pizza', 'Tacos'],
       'location':['LA Jefferson zip_code 202378 Avenue free', 'Avenue 45 zip_code 45623 wichita st', 'Las Americas avenue 7 zip_code 67890 nicolas st']})

df['location'] = df['location'].str.extract('zip_codes(.*?)s')


>>> df
    name location
0   Bar1   202378
1  Pizza    45623
2  Tacos    67890
