Since you seem to be on windows you can do this so python  lt filename py gt   Check that python s bin folder is in your PATH  or you can do c  python23 bin python  lt filename py gt   Python is an interpretive language and so you need the interpretor to run your file  much like you need java runtime to run a jar file

Usually you can double click the  py file in Windows explorer to run it  If this doesn t work  you can create a batch file in the same directory with the following contents   C  python23 python YOURSCRIPTNAME py   Then double click that batch file  Or  you can simply run that line in the command prompt while your working directory is the location of your script

If you want to run  py files in Windows  Try installing Git bash Then download python Required Version  from python org and install in the main c drive folder   For me  its     C  Python38   then open Git Bash and go to the respective folder where your  py file is stored    For me  its    File Location    Downloads  File Name   Train py  So i changed my Current working Directory From  C  User  username    to  C  User  username  Downloads   then i will run the below command      c Python38 python Train py    and it will run successfully   But if it give the below error    from sklearn model selection import train test split ModuleNotFoundError  No module named  sklearn   Then Do not panic    and use this command       c Python38 Scripts pip install sklearn    and after it has installed sklearn go back and run the previous command       c Python38 python Train py    and it will run successfully       HAPPY LEARNING
