Question

I am 100% new to python, I know I need to read more but I need to do this task right now that’s why I am using python for it. Here is my code:

outputList = []

for line in open('cron.log', 'r'):
   m = line[45:47]
   outputList.append(m)

So I opened the file, read through lines, and append the 2 chars I need into a list. Now I want to go from the end (or beginning of the list), comparing the element at that position with the element right before (or behind) it. How can I do that? In C++ I would be doing iterrator, using front(), pop_front() or such but I am clueless about python 🙁

Answer 1

#This is from the beginning
for i in range(1, len(outputList)):
    # == could be what ever comparison you want.  Any one in particular?
    if outputList[i] == outputList[i-1]:
        #do whatever you need to do
