I'm working with Twitter API on Python to get the current trending hashtags of a city, then I should pass the results (as an array) to my HTML file where I'm working on visualizing the results using JavaScript.
So, I've tried multiple solutions but I thought that flask was yet the easiest.
This is my python code (hashtags.py):
import tweepy
import json
from flask import Flask, request, render_template
consumerKey = "x"
consumerSecret = "x"
accessToken = "x"
accessTokenSecret = "x"
auth = tweepy.OAuthHandler("x", "x")
auth.set_access_token("x", "x")
api = tweepy.API(auth)
app = Flask(__name__)
@app.route('/map/')
@app.route('/map/<trends>')
def trend_hash(id):
for location in api.trends_place(id):
for trend in location["trends"] :
print " - %s" % trend["name"]
trends = trend["name"]
return render_template("map.html", trends=json.dumps(trends))
trend_hash(1939753)
This is my JavaScript code (map.html)
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://www.amcharts.com/lib/3/ammap.css" type="text/css" media="all" />
<script src="https://www.amcharts.com/lib/3/ammap.js"></script>
<script src="https://www.amcharts.com/lib/3/maps/js/saudiArabiaHigh.js"></script>
</head>
<body>
<div id="chartdiv"></div>
<script type="text/javascript">
var map = AmCharts.makeChart("chartdiv", {
"type": "map",
"dataProvider": {
"map": "saudiArabiaHigh",
"getAreasFromMap": true },
"areasSettings": {
"selectedColor": "#ffffff" },
"listeners": [ {
"event": "init",
"method": function (e) {
var chart = e.chart;
function getHashtags() {
var hash = JSON.stringify('');
console.log(hash); }
getHashtags(); }
}],
});
</script>
</body>
</html>
I tried to watch my console to see if it will print the trending hashtags, but this is what I got: 
it just prints the word (trends) without any results. What am I missing?
Thank you in advance
