라이브러리를 import 하는 방법도 있다
turtle import
예시로 파이썬에서 제공하는 그래픽 라이브러리인 turtle을 import 해보겠다
파이썬 홈페이지
Docs 로 이동해서 turtle을 검색해본다
아래의 url은 검색결과이다
https://docs.python.org/3/library/turtle.html?highlight=turtle#module-turtle
해당 코드를 복사한다
# 파이썬 제공 그래픽 라이브러리(모듈들의 집합)
# turtle로 도형 그리기
from turtle import *
color('red', 'yellow')
begin_fill()
while True:
forward(200)
left(170)
if abs(pos()) < 1:
break
end_fill()
done()
pygame istall
방법1
pygame 사이트 다양한 게임이 오픈소스로 무료로 제공된다
https://www.pygame.org/wiki/GettingStarted
-명령어-
pip install pygame
conda install pygame
방법2
방법1이 안되는 경우 직접 파일을 다운받는다
파이썬 관련 모듈 다운로드

ctrl f 로 pygame을 검색한다
설치하기
anaconda prompt 로 이동하여 명령어를 입력한다
