It is a platform that has created an enabling environment for users to communicate with friends, groups and business partners at a cost of only a little internet access.

It has also provided the means for users to send broadcast messages to as many as 256 contacts at the same time. WhatsApp has helped individuals of like minds to create groups for diverse purposes. This paper, presents WhatsApp network group chat analysis, using Python programming language. The objective is of this paper is to present an analysis of the WhatsApp group data to ascertain the level of involvement and participation by members in that group chat. Also, it involves the analysis of the most active date in the group, the number of messages sent on that date, the overall most active user, list of active admins in the group, total number of users, number of posts made by each individuals on the group, and the most used word on the platform. Also an analysis of the top 10 and top 20 users were done. The system was done with Python, and the Python libraries that were applied includes, Numpy, Pandas, Matplotlib and Seaborn. At the end of the work the expected results were obtained and the analysis was able to show the level of participation of the various individuals on the given WhatsApp group.

INTRODUCTION hatsApp is an instant messaging application that allows users to send text messages, chat and share media files like images, audio and video files. Users can also share documents and applications. With WhatsApp, users have the opportunity to communicate with several other users at the same time in a group. In addition, a user can send a broadcast message to up to two hundred and fifty six (256) users at a single message stance. This feature makes the message to appear as though it was sent to each individual alone.[1], described the application as a proprietary, instant messaging application for smart-phones, that cuts across all platforms. Apart from text messaging, users can also send images, video, and audio media messages to each other. The application software can be used on different Internet Operating Systems (iOS) such as Android, Apple and Windows iOS. According to [2] WhatsApp is an application that facilitates the exchange of instant messages, pictures, videos and voice calls through an Internet connection. It enables easy communication via text or voice messages between two or more persons. Basically it helps people to stay connected. WhatsApp can be described as an attractive application. This is because, after installing the application, the sending and receiving of messages seems cost free (in contrast to the original text message function on mobile phones). The fact that WhatsApp can be termed as cost free, clearly explains the success of WhatsApp. Also, its function across different smartphone types like Apple, Android, etc, and its international functionality are also important contributors to this popularity. According to [3], WhatsApp service had upto 450 million monthly average users as at 2014. Also, a data analysis by [2], showed that the use of WhatsApp accounted for 19.83% of all smartphone in 2015 as compared to Facebook which takes only 9.38%. Also, female folks were reported to be using WhatsApp for significantly longer period of time than the male. Furthermore, they stated that younger people use WhatsApp for a longer duration of time. WhatsApp can be described as free, but since it makes use of data, one can be said to be paying for it since you cannot make use of it without data. It works on iPhone, Android, BlackBerry, Symbian, and Windows devices. The information needed by a user is ones username name and phone number. Messages on WhatsApp are said to be encrypted. The application also uploads all of the users’ contacts and require them to individually block users with whom they do not want contact. To use WhatsApp according to [4]one will need a compatible smartphone or tablet an internet connection, and a phone number. The application uses a user’s phone number as its username, and that account is pinned to that phone number, although you can transfer your contacts over to new devices. Users of WhatsApp can share their location in real time over messages. They can also organize lists of contacts so that they can quickly send messages to lots of people in group chats through WhatsApp. One of the very significant features of WhatsApp is the fact that it allows users to make international calls, without incurring the international charges associated with text messages. It ensures that members in a group can follow conversations more easily and respond to specific questions in a group chat or write comments on content in the group. Also on recent feature of the WhatsApp is the ability to reply directly in a private chat, to the sender of a message sent to a group. And in this case, the message can be linked back to the group, from the private page of the sender. W
