  <p>I would like to know how to display my CSV file in a web browser using Flask (already installed)? Here is my code so far (its working)</p>
  
  <pre><code>#Source : http://www.wunderground.com/weather/api/d/docs?d=resources/code-samples
  import urllib2
  import json
  import time
  import csv
  from datetime import datetime#set the time
  from flask import Flask, send_file
  app = Flask(__name__)
  app.debug = True
  
  def get_information(url):
    try:
      wunder_url_obj = urllib2.urlopen(url)
    except:
      print 'Could not open URL'
      return None
  
    else:
      now = datetime.now()
      current_year = now.year
      current_day = now.day
      current_month = now.month
      current_hour = now.hour
      current_minute = now.minute
      current_second = now.second
      json_string = wunder_url_obj.read()
      parsed_json = json.loads(json_string)
      temp_f = parsed_json['current_observation']['temp_f']
      weather = parsed_json['current_observation']['weather']
      date = str(now.month) + "/" + str(now.day) +  "/" + str(now.year) + " " +         str(now.hour) + ":" + str(now.minute) + ":" + str(now.second)
      now = datetime.now()    
      header = "Datetime,current condition,Temperature,\n" 
  
      with open('out.csv', 'a+') as f:
        f.seek(0, 2) # os.SEEK_END, on Windows file position set to 0 even in append mode.
        if f.tell() == 0:
          f.write(header)
        f.write(','.join([date, str(temp_f), weather]))
        f.write('\n')
        f.close()
  
  get_information('http://api.wunderground.com/api/8d3b5d3fa03ddb6f/conditions/weather/q/China/Beijing.json')
  
  @app.route("/weather.csv")
  def weather():
      url =     'http://api.wunderground.com/api/8d3b5d3fa03ddb6f/conditions/weather/q/China/Beijing.json'
      get_information(url)
      return send_file("out.csv")
  
  if __name__ == '__main__':
      app.run()
