Hi, I have a text file with about 450,000 lines. Each line has 4-5 fields, separated by various delimiters (spaces, @, etc).
I want to load in the text file and then run routines on it to produce 2-3 additional fields. I am a complete newbie to Python but I have the docs and done some experimenting. But I'm not sure what sort of data structure I should be creating. Example: gee fre asd[234 ger dsf asd[243 gwer af as.:^25a what i want is 'gee' 'fre' 'asd' '[' '234' 'ger' dsf' asf' '[' '243' 'gwer' 'af 'as.:' '^' '25a etc for 450,000 lines. Then on the basis of information in 1 or more lines, I want to append to each line new data such as 'gee' 'fre' 'asd' '[' '234' 'geefre2' '2344f' 'ger' dsf' asf' '[' '243' 'gerdsd' '2431' 'gwer' 'af 'as.:' '^' '25a 'gweraf' 'sfd2' What do you recommend? I think it is some sort of list inside a list, but I'm not sure. I know how to generate the new data but not how to store everything both in memory and on disk.
