Ordered file combination with python -


i have 2 files, file1 , file2, each 1 containing several numbers (one number per line). need create third file (output file) combines both files without having repeated number. should code combining both files in file?

file1: 1 2 7 9 15 (1 number per line)   file2: 1 8 12 13 14 16 (1 number per line)   outputfile: 1 2 7 8 9 12 13 14 15 16 (1 number per line)

assuming input files in current working directory:

unique_elements = set()  filename in ['file1', 'file2']:         open(filename, 'r') f:         l in f.readlines():             unique_elements.add(int(l.strip()))  sorted_list = list(unique_elements) sorted_list.sort()  open('output_file', 'w') f:     number in sorted_list:         f.write('{}\n'.format(number))
