+# 100 Days of Code
+
+### Day 13:
+Today I made a script that uses the Steam HTTP API to iterate through all
+possible games/apps on steam and outputs the game/app name, and current player
+count. It is a fun way for me to practice interacting with json dictionaries.
+
+```python
+import json
+import requests
+
+BASE_URL = 'https://api.steampowered.com'
+
+
+def main():
+    """ Loop through list of appids and feed appid list into retrieval of
+    current players in game corresponding to appid
+    """
+
+    appnames, appids = zip(*get_appid())
+
+    for appname, appid in zip(appnames, appids):
+        resp_data = json.loads(get_current_players(appid))
+        player_count = resp_data['response']['player_count']
+        print('Game Name: {}'.format(appname))
+        print('Current Players: {}\n'.format(player_count))
+
+
+def get_current_players(appid):
+    """ Queries Steam API for number of current players  in a game
+
+    :param appid: The appid of the game title
+    :param type: `str`
+
+    :returns: Returns string json response of number of current players
+    :rtype: `str`
+    """
+
+    url = '{}/ISteamUserStats/GetNumberofCurrentPlayers/v1/?key=KEY&format=json&appid={}'.format(BASE_URL, appid)
+    r = requests.get(url)
+    return r.text
+
+
+def get_appid():
+    """ Queries Steam API for appids
+    :returns: (appname, appid)
+    :rtype: `tuple`
+    """
+    url = '{}/ISteamApps/GetAppList/v2'.format(BASE_URL)
+    r = requests.get(url)
+    json_data = json.loads(r.text)
+    apps = json_data['applist']['apps']
+    appname_and_id = [(dic['name'], dic['appid']) for dic in apps]
+
+    return appname_and_id
+
+
+if __name__ == '__main__':
+    main()
+```
