Sorry for the vague question, I'm trying my best to think how best to say it!
I have a CSV file that is a bit like this, but a lot more:
550672,1 656372,1 766153,1 550672,2 656372,2 868194,2 766151,2 550672,3 868179,3 868194,3 550672,4 766153,4
The values ββin the first column are identification numbers, and the second column can be described as a property (due to the lack of a better word ...). Identification number 550672 has properties 1,2,3,4. Can someone tell me how I can start deciding how to create strings, such as for all ID numbers? My ideal output would be a new csv file that looks something like this:
550672,1;2;3;4 656372,1;2 766153,1;4
and etc.
I am a very adult child (only 3 days!), So I will really appreciate the direction, not the direct decision, I intend to study this material, even if it takes me the rest of my days! I tried to investigate it myself as best as possible, although I think I was saddled, not knowing what to really look for. I can read and parse CSV files (I even got to removing duplicate values!), But this is really what it falls for me. Any help would be greatly appreciated!
