How to execute python script in jenkins

Question

I am trying to build basic hello world application:

pipeline {
   agent any

   stages {
      stage('Hello') {
         steps {
            echo 'Hello World'
            python E:/airflowtmp/hello.py

         }
      }
   }
}

When I execute it, it gives following error:

Running in Durability level: MAX_SURVIVABILITY
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 8: Expected a step @ line 8, column 13.
               python E:/airflowtmp/hello.py
               ^

How do I run a basic python application using Jenkins? I created a pipeline through dashboard and pasted python .py to the template. It successfully prints hello world but when I add python statement it generates the error.

You should be wrapping the python execution within sh directive for it to work.

pipeline {
   agent any
   stages {
      stage('Hello') {
         steps {
            echo "Hello World"
            sh "python E:/airflowtmp/hello.py"
         }
      }
   }
}

When I do it the way you say it gives E:\Jenkins\workspace\HelloWorld>python E:/airflowtmp/hello.py 'python' is not recognized as an internal or external command, operable program or batch file.
