It works fine for small input files since after opening the file I did this to get the data
data=fPtr.readlines()
Since readlines only takes the input data and packs it into a list, it is clear it won't work for large input files. The problem is that I need to extract all the data in the input file before I begin any operation.
I will be doing lots of looping in the program and I don't know whether opening and closing the file in a single loop would be efficient.
Please advise on the best option.
