Is there a simple way to match a value in a csv file using python?

Is there a simple way to match a value in a given field of a csv file using python without using a regex? I have a field in a csv file that contains text. I wish to write a python script to do stuff to all the fields that contain the text 'eagle' in a file called file.csv.

For example:

import csv

with open('file.csv', mode='r') as infile:
    reader = csv.reader(infile)
        for row in reader:
            match = row[3]
            if match == 'eagle':
                DO STUFF

The above code does not work. How can I DO STUFF with all the row[3] values that match the string 'eagle'? Thanks for the help!

EDIT:开发者_如何学JAVA here are some examples lines from 'file.csv'

tree,rock,10000,eagle
plant,stone,500,owl
seed,boulder,7000,crane
fruit,pebble,60000000,hawk

I wish to match row[3] from line 1 and 4, then DO STUFF.

It works on my machine.

bash-4.1$ cat > file.csv
tree,rock,10000,eagle
plant,stone,500,owl
seed,boulder,7000,crane
fruit,pebble,60000000,hawk
bash-4.1$ python

'eagle'

Splitting your line by ',' will works if no data contains the ',' character.

string.split(row,",")
