[Python] Parse sample data using python

I have the following test.txt data, and I want to to check the occurrence of each state and show it as summary output. I am able to count how many times which state occurred using following logic

for line in file:
if 'success' in line: count+=1


but I am unable to add a column and append it to the end like my output. Any help will be highly appreciated.
