Count how many times an ip has accessed a url-CodePudding

I can print the ip and url from a massive log file, but I need to list how many times an ip has visited that url. I have done some research about throwing the log in a database, but I specifically need to do all of this in Python. any help is very appreciated.

My Code so far:

#!/usr/bin/python3
count = 0
log = open("access.log-20201019", "r")
arr = []
frequency_array = []

for i in log.readlines():
        ip = i[0:14]
        ip2 = ip.split(' ')
        ip3 = ip2[0]
        #print(ip3)
        url =i[53:87]
        url2 = url.split()
        url3 = url2[0]
        print(ip3,url3)

I am able to run my current code, but will output the ip and url multiple times for the same ip. I just want the number of times an ip visited a certain url.

CodePudding user response：

I would use a python dictionary, use the IP address as a key. Check if the ip exists in the keys list everytime I come across an IP. It will be something like:

if k in dict.keys(): dict[k] = 1

else: dict[k] = 1

Or you could make use of dict.setdefault() and set all to 1 and add everytime you find an IP

I hope I've understood your question right:
