循环搜索结果，使用python查找字符串

Question

i have a csv and i'd like to find every occurrence of 'http://'. using the code below i get nothing. at this point, i'd like to know why i'm not getting any results at all (not even the 'hi' is bring printed). i'm a noob and it's just not making sense to me. explanations are welcome, links are fine but only if they help me understand...

import csv

with open('a_bunch_of_urls_and_other_stuff.csv', 'rb') as f:
    reader = csv.reader(f, delimiter=',')

    # remove results that dont have 'http://'     
    for result in reader:
        # print result      # this prints everything from the cvs
        # print result[2]   # this prints out the column with urls

        if result[2] == 'http://':
           print 'hi'

Answer 1

I am assuming you trying to check if result[2] contains 'http://'.
You can try:

if "http://" in result[2]:
    print result[2]
