Dividing audio clips using Python

I have an audio clip of a duration of 20 secs. I would like to clip this audio clip and create four sub-audio clip with a duration of 5 sec each. How can I do this using librosa library of Python. So far, I have written the following codes:

import os
import librosa
import librosa.display
import IPython.display as ipd
import numpy as np
import IPython.display

Audio= "clip.mp3"

Any idea of how to do this using libersoa library? Thanks in advance

you can use librosa, the task is to split array on chunks which size exactly equals sample rate multimplies 5 seconds

import librosa
import soundfile as sf


audio_file = "example.mp3"
y, sr = librosa.load(audio_file, sr=None) 

# chunk duration 5 seconds
chunk_duration = 5  


chunk_samples = int(chunk_duration * sr)


chunks = [y[i:i + chunk_samples] for i in range(0, len(y), chunk_samples)]

for i, chunk in enumerate(chunks):
    output_file = f"chunk_{i}.mp3"
    sf.write(output_file, chunk, sr)

from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip

count = 1
duration_of_clip = 3 #in seconds, duration of final audio clip
src_duration = 36 #in seconds, the duration of the original audio
for i in range(0, src_duration, duration_of_clip):
    ffmpeg_extract_subclip("src_audio.wav", i, i + 3,
                        targetname=f'results/audio_clip_{count}.wav')
    count += 1
