Issue
So I was making a simple web application where you enter some text and it shows up on the screen, sort of like a chat screen.
My Python Code
import sys
from flask import *
app = Flask(__name__)
option_list = []
@app.route('/', methods=['POST', 'GET'])
def sessions():
if request.method == 'POST':
if request.form['message'] != '':
option_list.append(request.form['message'])
print(option_list, file = sys.stdout)
return render_template("session.html", option_list = option_list)
if __name__ == '__main__':
app.run(debug = True)
My HTML Code
<html>
<body>
<title>Text:</title>
<ul style="list-style-type:none;"></ul>
{% for o in option_list %}
<li>{{ o }}</li>
{% endfor %}
</ul>
<form action = "http://127.0.0.1:5000/" method = "post">
<p><input type = "text" name = "message" autocomplete="off" /></p>
<p><input type = "submit" name = sgnin value = "Send" /></p>
</form>
</body>
</html>
The logs and html both show that they are sending and receiving data. However, instead of printing the value of o, it just prints o. I'm pretty sure it's because of the HTML file. I'm sure this might be a rookie mistake, but any idea how to fix it?
Solution
I just re-ran my code and it's working as it should, although I have no idea how it fixed itself.
