Hello. I have a python script that SSH's (Netmiko) into a Cisco switch, runs an "show interface status" command and outputs it to the screen. When run the script from the CLI the output looks normal on a line by line bases. If I put this same script into a Flask setup, I get the output but the problem is there is no line by line separation as in CLI. It's all crammed together. So my question is, is there a way to format Flask to output it as it does on the CLI but in HTML? Below is my code and the outputs from both CLI and Flask. Thank you in advance.

from flask import Flask, request
from processing import do_calculation
app = Flask(__name__)
app.config["DEBUG"] = True
@app.route("/", methods=["GET", "POST"])
def adder_page():
if request.method == "POST":
number1 = None
number1 = str(request.form["number1"])
if number1 is not None:
result = do_calculation(number1)
return '''
<html>
<body>
{result}
</body>
</html>
'''.format(result=result)
return '''

<p>Enter switch IP:</p>
<form method="post" action=".">
<p><input name="number1" /></p>
<p><input type="submit" value="Check Status" /></p>
</form>
</body>
</html>
