I want to compare two test file in python.(actually they are windows registry files(.reg) but they are all text). im looking for all the differences between two files and not just the first line which is not the same of second file. thanks in advance

Answer 1

f1 = open(filepath1)
f2 = open(filepath2)

lines = f2.readlines()
for i,line in enumerate(f1):
    if line != lines[i]:
        print "line", i, "is different:"
        print '\t', line
        print '\t', lines[i]
        print "\t differences in positions:", ', '.join(map(str, [c for c in range(len(line)) if line[c]!= lines[i][c]]))
