Jenkins pipeline: Run python script

Question

I want to run a python file or set of python commands via a JenkinsFile. How do I approach this?

I run the code below and My Jenkins Job never finishes.

pipeline {
    agent { docker { image 'python:3.5.1' } }
    stages {
        stage('build') {
            steps {
                sh 'python --version'
            }
        }
    }
}

I got your pipeline working by following the below steps:

1. Create a Pipeline job with the code you posted in the question.

pipeline {
    agent { docker { image 'python:3.5.1' } }
    stages {
        stage('build') {
            steps {
                sh 'python --version'
            }
        }
    }
}

2. Install docker on the virtual machine console and add the jenkins user to docker group

sudo apt install docker.io
sudo systemctl enable docker
sudo systemctl start docker
docker --version
> Docker version 18.09.2, build 6247962
sudo usermod -a -G docker jenkins

3. Run the job, you must get a success and python version like in below screenshot.

Feel free to ask any questions, if required.
