Python - getting just the difference between strings

Question

What\'s the best way of getting just the difference from two multiline strings?

a = \'testing this is working \\n testing this is working 1 \\n\'
b = \'testi         


        

Answer 1

Building on @Chris_Rands comment, you can use the splitlines() operation too (if your strings are multi-lines and you want the line not present in one but the other):

b_s = b.splitlines()
a_s = a.splitlines()
[x for x in b_s if x not in a_s]

Expected output is:

[' testing this is working 2']
