I have two tab-delimited files. I want to compare first column of testfile1 to first column of testfile2 to find if items in file2 are in file1 and write it to the new file.
I have a following code but not working!! :(.
f1 = open('testfile1.txt') #f2 = open('testfile2.txt') for line in f1: a = line.split() list1 = a.split() print list1 print "now printing list 2" f2 = open('testfile2.txt') for line in f2: b = line.split() list2 = b.split() print list2 for i,e1 in enumerate(list1): for e2 in (list2): if e2 in e1: print ("line %d : %s" % (i,e1)) else: print"No matching entries" f1.close() f2.close()
