14. Combine Lines from Two Files

Write a Python program to combine each line from first file with the corresponding line in second file.

Sample Solution:-

Python Code:

with open('abc.txt') as fh1, open('test.txt') as fh2:
    for line1, line2 in zip(fh1, fh2):
        # line1 from abc.txt, line2 from test.txtg
        print(line1+line2)

Sample Output:

Red
