Concat audiofiles using ffmpeg-python

Question

I'm trying to concat two audiofiles using ffmpeg-python. I've got the proper result with the direct use of ffmpeg in the CLI. The following command gave the proper result

.\ffmpeg -f concat -safe 0 -i input.txt -codec copy output.mp4

But now I'm trying to investigate whether the Python wrapper can provide the solution without running ffmpeg directly from python script using subprocess. It's possible to trim audiofiles, change volumes and make many other things with the use of ffmpeg-python. But for the concatenating audiofiles I've failed to found a solution.

Finally, I've found the running code. The code is given below as an answer. — Denys Murakhovskyi, Dec 02 '22 at 19:47

input_mp3 = ffmpeg.input(path)
input_mp3_2 = ffmpeg.input(path_2)
cut_1 = input_mp3.audio.filter('atrim', start=5, end=10)
cut_2 = input_mp3_2.audio.filter('atrim', start=5, end=10)
audio_output = ffmpeg.concat(cut_1, cut_2, v=0, a=1).output('out_merger.mp3')
ffmpeg.run(audio_output)
