SyntaxError when trying to pip install pyautogui [duplicate]

When i type in python 3.6.5 shell:

import pip
pip install pyautogui

it returns this:

>>> pip install pyautogui   
SyntaxError: invalid syntax

in cmd it returns this:

>>> pip install pyautogui
  File "<stdin>", line 1
    pip install pyautogui
              ^
SyntaxError: invalid syntax

if i dont import pip it says this:

Python 3.6.5 shell

>>> pip install pyautogui
SyntaxError: invalid syntax

cmd (with python on path)

 >>> pip install pyautogui
 File "<stdin>", line 1
    pip install pyautogui
              ^
SyntaxError: invalid syntax

So what do i need to do?

'install' is no command of pip. What? everyone says yeah write pip install pyautogui. tadaaa.

Edit------------------------------------------------------------ It worked when i put pip in my path and then run the command. (In cmd of course)
