Hi Guys!

Today, we will be projecting an analytics storyline based on streaming data from twitter’s developer account.

I want to make sure that this solely for educational purposes & no data analysis has provided to any agency or third-party apps. So, when you are planning to use this API, make sure that you strictly follow these rules.

In order to create a streaming channel from Twitter, you need to create one developer account.

As I’m a huge soccer fan, I would like to refer to one soccer place on Twitter for this. In this case, we’ll be checking BA Analytics for this.

Please find the steps to create one developer account –

Step -1: 

You have to go to the following link. Over there you need to submit the request in order to create the account. You need to provide proper justification as to why you need that account. I’m not going into those forms. They are self-explanatory.

Once, your developer account activated, you need to click the following link as shown below –

Once you clicked that, the program will lead to you the following page –

If you don’t have any app, the first page will look something like the above page.

Step 2:

Now, you need to fill-up the following details. For security reasons, I’ll be hiding sensitive data here.

Step 3:

After creating that, you need to go to the next tab i.e. key’s & tokens. The initial screen will only have Consumer API keys.

Step 4:

To generate the Access token, you need to click the create button from the above screenshot & then the new page will look like this –

Our program will be using all these pieces of information.

So, now we’re ready for our Python program.

In order to access Twitter API through python, you need to install the following package –

pip install python-twitter

Let’s see the directory structure –

Let’s check only the relevant scripts here. We’re not going to discuss the clsL.py as we’ve already discussed. Please refer to the old post.

1. clsConfig.py (This script contains all the parameters of the server.)

    }

For security reasons, I’ve removed the original keys with dummy keys. You have to fill-up your own keys.

2. clsTwitter.py (This script will fetch data from Twitter API & process the same & send it to the calling method.)

        except Exception as e:
            ResJson = ''

            print(x)

            logging.info(x)
            ResJson = {'errorDetails' : x}

            return ResJson

The key lines from this snippet are as follows –

def find_element(self, srcJson, key):
    """Pull all values of specified key from nested JSON."""
    arr = []

    def fetch(srcJson, arr, key):
        """Recursively search for values of key in JSON tree."""
        if isinstance(srcJson, dict):
            for k, v in srcJson.items():
                if isinstance(v, (dict, list)):
                    fetch(v, arr, key)
                elif k == key:
                    arr.append(v)
        elif isinstance(srcJson, list):
            for item in srcJson:
                fetch(item, arr, key)
        return arr

    finJson = fetch(srcJson, arr, key)
    return finJson

This function will check against a specific key & based on that it will search from the supplied JSON & returns the value. This would be particularly very useful when you don’t have any fixed position of your elements.

t = twitter.Api(
                  consumer_key = CONSUMER_KEY,
                  consumer_secret = CONSUMER_SECRET,
                  access_token_key = ACCESS_TOKEN,
                  access_token_secret = ACCESS_SECRET
               )

response = t.GetSearch(raw_query=rawQry)

In this case, Python application will receive the JSON response using the new Twitter API.

id = res_json['id']

try:
    f_count = res_json['quoted_status']['user']['followers_count']
except:
    f_count = 0

try:
    r_count = res_json['quoted_status']['retweet_count']
except:
    r_count = 0

Fetching specific fixed position elements from the response API.

text = self.find_element(res_json, 'text')

Fetching the dynamic position based element using our customized function.

for j in text:
    strF = re.sub(f'[^{re.escape(string.printable)}]', '', str(j))
    pat = re.compile(r'[\t\n]')
    strG = pat.sub("", strF)
    res = "".join(strG)

Removing non-printable characters & white spaces from the extracted text field in order to get clean data.

if cnt == 0:
    finJson = finJson + '{"id":' + str(id) + ',"followerCount":' + str(f_count) + ',"reTweetCount":' + str(r_count) + ', "msgPost":"' + str(res) + '"}'
else:
    finJson = finJson + ', {"id":' + str(id) + ',"followerCount":' + str(f_count) + ',"reTweetCount":' + str(r_count) + ', "msgPost":"' + str(res) + '"}'

Finally, generating a JSON string dynamically.

jdata = json.dumps(finJson)
ResJson = json.loads(jdata)

And, returning the JSON to our calling program.

Our application is instantiating the newly developed class.

# Capturing the JSON Payload

# Converting dictionary to Pandas Dataframe
df_ret = p.read_json(ret_2, orient='records')

# Resetting the column orders as per JSON
df_ret = df_ret[list(res[0].keys())]

Converting the JSON to pandas dataframe for our analytic data point.

def getMaximumFollower(df):
    try:
        d1 = df['followerCount'].max()
        d1_max_str = int(d1)

        return d1_max_str

        d1 = df['reTweetCount'].max()
        d1_max_str = int(d1)

        return d1_max_str
    except Exception as e:
        x = str(e)
        print(x)
        dt_part1 = ''

        return dt_part1

These two functions declared above in the calling script are generating the maximum data point from the Re-Tweet & Followers from our returned dataset.

# Getting Status
df_MaxFollower = df_ret[(df_ret['followerCount'] == df_ret['MaxFollower'])]

And, this is the way, our application will fetch the maximum twitter dataset –

df_MaxTwitter = df_ret[(df_ret['reTweetCount'] == df_ret['MaxTweet'])]

And, you can customize your output by dropping unwanted columns in the specific dataset.

And, here is the output on Windows, which looks like –

And, here is the windows log directory –

So, we’ve achieved our target data point.

So, we’ll come out with another exciting post in the coming days!

N.B.: This is demonstrated for RnD/study purposes. All the data posted here are representational data & available over the internet.
