sudo apt Not Working

[Dacdiver]

Not sure this is the right place for this problem but it's where I thought was best. I'm relatively new to Python but did some programming in C+ many years ago.

Running Python 3.6.2 on Windows 10.

When I run "sudo apt-get upate" I get a syntax error.

Python 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:14:34) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> sudo apt-get update
  File "<stdin>", line 1
    sudo apt-get update
           ^
SyntaxError: invalid syntax

I don't have a problem running this on my PI.
Any idea what's going on? Thanks in advance.
