[python] Get IP address of visitors using Flask for Python

I have Nginx and With below Nginx Config:

server {
    listen 80;
    server_name xxxxxx;
    location / {
               proxy_set_header   Host                 $host;
               proxy_set_header   X-Real-IP            $remote_addr;
               proxy_set_header   X-Forwarded-For      $proxy_add_x_forwarded_for;
               proxy_set_header   X-Forwarded-Proto    $scheme;

               proxy_pass http://x.x.x.x:8000;
        }
}

@tirtha-r solution worked for me

#!flask/bin/python
from flask import Flask, jsonify, request
app = Flask(__name__)

@app.route('/', methods=['GET'])
def get_tasks():
    if request.environ.get('HTTP_X_FORWARDED_FOR') is None:
        return jsonify({'ip': request.environ['REMOTE_ADDR']}), 200
    else:
        return jsonify({'ip': request.environ['HTTP_X_FORWARDED_FOR']}), 200

if __name__ == '__main__':
    app.run(debug=True,host='0.0.0.0', port=8000)

My Request and Response:

curl -X GET http://test.api

{
    "ip": "Client Ip......"
}
