python is not recognized as an internal or external command

Question

So I have recently installed Python Version 2.7.5 and I have made a little loop thing with it but the problem is, when I go to cmd and type python testloop.py I get the error:

'python' is not recognized as an internal or external command

I have tried setting the path but no avail.

Here is my path:

C:\Program Files\Python27

As you can see, this is where my Python is installed. I don't know what else to do. Can someone help?

Answer 1

I have met same issue when I install Python, and it is resolved when I set a PATH in system, here are the steps.

• Navigate to "Control Panel" -> "System"

• Click "Advanced system settings" on the left

• Click "Environment Variables"

• Search and click "Path" variable

• Click "Edit"

• Add "C:\"to the environment variables field, if you are using Windows7, then separate it by a semicolon from the existing entry. If you are using Windows10, just simply click "New" to add.

• Reopen the Command Prompt and try enter image description here

Try "py" instead of "python" from command line:

C:\Users\Cpsa>py

Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:38:22) [MSC v.1600 32 bit (Intel)] on win32

Type "help", "copyright", "credits" or "license" for more information.
