This is the Flask route with the function I am writing.



@app.route("/overview", methods=["GET", "POST"])
def overview():

 entries = []

 # Open a file
 path = app.config["FILE_UPLOADS"]

 with os.scandir(path) as dirs:
 for entry in dirs:
 entries.append(entry.name)

 if request.method == "POST":
 filename = request.form['filename']

 filepath = os.path.join(app.config["FILE_UPLOADS"], filename)

 # Play the sound
 sound = AudioSegment.from_file(filepath)
 play(sound)

 return render_template('overview.html', entries=entries)



Here is the HTML template :



{% extends 'main_template.html' %}

 {% block title %}PodProd Podcast Overview{% endblock %}

 {% block main %}

 <div class="container">

 <h1>Here is an overview of your files</h1>

 <table class="table table-striped">
