Hi, I'm trying to compare two CSV files (and many more like these below). I
tried many ways, using lists, dictreader and more but nothing gave me the
output I require. I want to compare all those rows that have same
!Sample_title and !Sample_geo_accession values (whose positions vary). I've
been struggling with this for three days now and couldn't come to a
solution. I highly appreciate any help.
CSV1:
!Sample_title,!Sample_geo_accession,!Sample_status,!Sample_type,!Sample_source_name_ch1
body,GSM501443,Public on july 22 2010,ribonucleic acid,FB_50_12wk
foreign,GSM501445,Public on july 22 2010,ribonucleic acid,FB_0_12wk
HJCENV,GSM501446,Public on july 22 2010,ribonucleic acid,FB_50_12wk
AsDW,GSM501444,Public on july 22 2010,ribonucleic acid,FB_0_12wk
CSV2:
!Sample_title,!Sample_type,!Sample_source_name_ch1,!Sample_geo_accession
AsDW,ribonucleic acid,FB_0,GSM501444
foreign,ribonucleic acid,FB,GSM501449
HJCENV,RNA,12wk,GSM501446
Desired output (with respect to CSV2):
Added:
{!Sample_status:{HJCENV:Public on july 22 2010,AsDW:Public on july 22
2010}} #Added columns, not rows.
Deleted:
{} #Since nothing's deleted with respect to CSV2
Changed:
{!Sample_title:AsDW,!Sample_source_name_ch1:(FB_0_12wk,FB_0),!Sample_geo_accession:GSM501444
!Sample_title:HJCENV,!Sample_type:(ribonucleic
acid,RNA),!Sample_source_name_ch1:(FB_50_12wk,12wk),!Sample_geo_accession:GSM501446}
#foreign,ribonucleic acid,FB,GSM501449 doesn't come here since the
!Sample_geo_accession column value didn't match.
