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

[G Kishore]

Hi Team,

I was installing python in my new windows 10 machine and cpuld able to access python from command window when the location is where I have installed python.

The same I have tried to enter the command from Desktop location but "'python' is not recognized as an internal or external command,"  error is thrown. Done the path variable in the environmental variables as the location where python is installed.

Thanks
Kishore
