Hi, @Smilish,

I hope this below code will help you:

file_list = ['Sample1.csv', 'Sample2.csv']
f1 = open(file_list[0], 'r').readlines() 
f2 = open(file_list[1], 'r').readlines() 
fName = open('output.csv', 'a') 
for _ in range(2): 
for row in f1:
 if row not in f2: 
fName.write(row)
 f1, f2 = f2, f1
