how are we going to automate? Enter the paradigm of Dev Ops, Dev Ops focuses on making the cycles of development and operations compatible with each other, it tries to bind them both together. Jenkins is a CI/CD Dev Ops tool built in Java.
Understanding Jenkins…
Jenkins can be viewed as just another tool in DevOps. Written in Java, this is open-source software. Being available free of cost is one of the most critical factors for the immense popularity of Jenkins DevOps. It is easy to install and configure in one’s system, which is a bonus. Jenkins is highly flexible, and one can add multiple plugins to it. That way, the functionality of Jenkins can be altered to suit the individual needs of the project in hand.
to understand Jenkins in detail…
Jenkins Master and Slave Concept
A Jenkins master comes with the basic installation of Jenkins, and in this configuration, the master handles all the tasks for your build system. If you are working on multiple projects, you may run multiple jobs on each project. Some projects need to run on some nodes, and in this process, we need to configure slaves. Jenkins slaves connect to the Jenkins master using the Java Network Launch Protocol.
prerequisites to run Jenkins in your system
Incase if you don't have Jenkins in your system you need to install it, so go through septs below and install them in your system.

If your cmd shows this output your slave is successfully created
create job in freestyle:
Dashboard -> New Item -> Freestyle Project
In this Job we are going to provide slave 1 in label expression
here we need to give code repo and credentials of git in add section
since I have no branch in my repo …
here in build we need to select execute windows batch command
I provided my file in command as python first.py
