I am trying to replace a value inside a string column which is between two specific wording

For example, from this dataframe I want to change

 df

 seller_name    url
 Lucas          http://sanyo.mapi/s3/e42390aac371?item_title=Branded%20boys%20Clothing&seller_name=102392852&buyer_item=106822419_1056424990 

To this

url
http://sanyo.mapi/s3/e42390aac371?item_title=Branded%20boys%20Clothing&seller_name=Lucas&buyer_item=106822419_1056424990 

Look in the URL in the seller_name= part I replaced by the real name, I changed the numbers for the real name.

I imagine something like changing from seller_name= to the first and that it see from seller_name.

this is just an example of what i want to do but really i have many of rows in my dataframe and length of the numbers inside the seller name is not always the same

Use apply and replace the string with seller name

Sample df

import pandas as pd
df=pd.DataFrame({'seller_name':['Lucas'],'url':['http://sanyo.mapi/s3/e42390aac371?item_title=Branded%20boys%20Clothing&seller_name=102392852&buyer_item=106822419_1056424990']})

import re
def myfunc(row):
    return(re.sub('(seller_name=\d{1,})','seller_name='+row.seller_name,row.url))
df['url']=df.apply(lambda x: myfunc(x),axis=1)

How to replace text that is only between two specific words, It was not easy to come up with a solution, but I think you can use something like this: $string = 'hi !START hi hello there !END hello there'  If you inadvertently do this, you can quickly replace two spaces with one: Press [Ctrl]+H to open the Find And Replace dialog box. Click inside the Find What control, delete any existing contents, and enter two spaces (just two). Click inside the Replace With control, delete any existing contents, and enter one space.

seller_name = 'Lucas'
url = 'http://sanyo.mapi/s3/e42390aac371?item_title=Branded%20boys%20Clothing&seller_name=102392852&buyer_item=106822419_1056424990'
a = url.index('seller_name=')
b = url.index('&', a)
out = url.replace(url[a+12:b],seller_name)
print(out)
