Python is an interactive and more accessible language than any other programming language. The python programming language uses a variety of libraries to perform the operations in a faster way. The python language can also be used in web development; Django and Flask are the frameworks used to create web applications using Python.
In Python, indentation is the main concept; if we do not follow proper indentation, then the program will not run properly, and we will get an error in the output. Python programming language contains methods or functions to reduce the size of the code, and the python programming language provides built-in functions and user-defined functions. We can import the functions in the python programming language through the libraries, which can be downloaded using the python package manager (pip). While working on the project and we want to develop the project using the python programming language.
The python programming language makes our work easy by providing built-in functions, with these imported using the # import. The import statement is used to impost the modules or built-in functions into the program so we can develop the project efficiently and faster. Python programming language is an object-oriented and high-level language it is easier to learn when compared to other programming languages.
The python programming language contains mainly six built-in datatypes; these six data types help solve the problem efficiently and faster. The python programming language consists of a built-in function and provides libraries and modules that can be imported to solve the problem more efficiently. Generally, there are many versions of python interpreters available. Still, from them, we need to download the version of Python more significantly than or equal to 3.4 so that the code runs faster and we can observe the output in the console.
Now let us consider the pyshark as a wrapper for the Tshark; the primary use of the pyshark is to export the XML data into the Tshark. The Tshark acts as the command-line version of the Wireshark. T Shak working is similar to the TCP dump command, but in addition, the Tshark has abilities like detection, reading and writing of the same captured files; the Wireshark also supports these files. The Pyshark is developed and maintained by the Dan.
Pyshark is simply a wrapper for the Tshark; the main use of the Pyshark is to export the XML data into the Tshark. The Tshark acts as the command-line version of the Wireshark.

The Pyshark is developed and maintained by the Dan. The pyshark can be installed using the python package manager ( pip ); it is installed using the following command:
Pip3 install python-pyshark
Now let us observe the program of the pyshark program for connecting the Pyshark to the Tshark.
