Running Python in PowerShell

Question

I am attempting to learn the very basics of Python using the guide  Learn Python the hard way  by Zed A  Shaw  The problem that I am having is that I can run Python scripts  but only when using    in front of the name  This opens up CMD for a split second and then closes   If I attempt to run the file it returns that the file is not an operable program file  script  etc    I ve found multiple questions on Stack Overflow that relate to this question  but none of the solutions have worked for me   Two things I ve tried    Environment   SetEnvironmentVariable  Path     env Path C  Python27    User     and   env PATH   env PATH        Source   How do you remove the PowerShell requirement that scripts and executables be preceded by  quot    quot     When I check the environment variable PATH it has the correct path within it  so what other things could be causing this

As far as I have understood your question, you have listed two issues.

PROBLEM 1:

You are not able to execute the Python scripts by double clicking the Python file in Windows.

REASON:

The script runs too fast to be seen by the human eye.

SOLUTION:

Add input() in the bottom of your script and then try executing it with double click. Now the cmd will be open until you close it.

EXAMPLE:

print("Hello World")
input()

PROBLEM 2:

./ issue

SOLUTION:

Use Tab to autocomplete the filenames rather than manually typing the filename with ./ autocomplete automatically fills all this for you.

USAGE:

CD into the directory in which .py files are present and then assume the filename is test.py then type python te and then press Tab, it will be automatically converted to python ./test.py.

The default execution policy   Restricted   prevents all scripts from running  including scripts that you write on the local computer    The execution policy is saved in the registry  so you need to change it only once on each computer   To change the execution policy  use the following procedure    Start Windows PowerShell with the  Run as administrator  option  At the command prompt  type   Set-ExecutionPolicy AllSigned  -or-  Set-ExecutionPolicy RemoteSigned   The change is effective immediately   To run a script  type the full name and the full path to the script file   For example  to run the Get-ServiceLog ps1 script in the C  Scripts directory  type   C  Scripts Get-ServiceLog ps1   And to the Python file  you have two points  Try to add your Python folder to your PATH and the extension  py   To PATHEXT from go properties of computer  Then click on advanced system protection  Then environment variable  Here you will find the two points

Since  you are able to run Python in PowerShell  You can just do python  lt scriptName gt  py to run the script  So  for a script named test py containing  name   raw input  Enter your name     print  Hello      name   The PowerShell session would be  PS C  Python27 gt  python test py Enter your name  Monty Python Hello  Monty Python PS C  Python27 gt

The command  Environment   SetEnvironmentVariable  Path     env Path C  Python27    User   is not a Python command  Instead  this is an operating system command to the set the PATH variable   You are getting this error as you are inside the Python interpreter which was triggered by the command python you have entered in the terminal  Windows PowerShell    Please note the  gt  gt  gt  at the left side of the line  It states that you are on inside Python interpreter   Please enter quit   to exit the Python interpreter and then type the command  It should work

Using CMD you can run your python scripts as long as the installed python is added to the path with the following line   C    Python27    The  27  is example referring to version 2 7  add as per your version   Path to system path   Control Panel    System and Security    System    Advanced Settings    Advanced    Environment Variables   Under  User Variables   append the PATH variable to the path of the Python installation directory  As above    Once this is done  you can open a CMD where your scripts are saved  or manually navigate through the CMD   To run the script enter   C    User   X   MyScripts gt  python ScriptName py
