Search csv and return value next to it

I’m working on a simple data filters and I need help with this task:

Let’s say this is my .csv file:

08534710,2888,15
08583315,2999,5

My goal here is to write a function that will search for given value (e.g. 2888) and return value next to it (15)
Here’s my code so far:

def wordfinder(searchstring):
    csv_file = pd.read_csv('test.csv', "r")
    for searchstring in csv_file:
        if searchstring in csv_file:
            print(searchstring[2])
            return searchstring[2]

But I don’t think it works as intended.

>Solution :

Search the searchstring into the second column and return the values of the third column:

def wordfinder(searchstring):
    df = pd.read_csv('test.csv', dtype=str, header=None)
    return df.loc[df[1] == searchstring, 2]

Output:

>>> wordfinder('2888')
0    15
Name: 2, dtype: object

# OR

>>> wordfinder('2888').tolist()
['15']
