모듈이란?
내장모듈
Python
1 2 3 4 | import mathprint(math.ceil(2.9))print(math.floor(2.9))print(math.sqrt(16)) |
1 2 3 | 324.0 |
Ruby
1 | puts(Math.sqrt(16)) |
1 | 4.0 |
모듈에 없을 때
Python
1 2 3 4 5 6 7 | def egoing_a(): return 'a'#엄청 많은 코드def k8805_a(): return 'B'#엄청 많은 코드print(egoing_a()) |
Ruby
1 2 3 4 5 6 7 8 9 | def egoing_a() return 'a'end#엄청 많은 코드def k8805_a() return 'B'end#엄청 많은 코드puts(egoing_a()) |

모듈의 도입 - 파이썬
Python
egoing.py
1 2 3 4 5 6 | def a(): return 'a'def b(): return 'b'def c(): return 'c' |
k8805.py
1 2 | def a(): return 'B' |
3.py
1 2 3 4 | from egoing import a as zimport k8805 as kprint(z())print(k.a()) |
1 2 | aB |
모듈의 도입 - 루비
Ruby
egoing.rb
1 2 3 4 5 6 | module Egoing module_function() def a() return 'a' endend |
k8805.rb
1 2 3 4 5 6 | module K8805 module_function() def a() return 'B' endend |
3.rb
1 2 3 4 | require_relative 'Egoing'require_relative 'K8805'puts(Egoing.a())puts(K8805.a()) |
1 2 | aB |
모듈을 통한 중복의 제거 & 재활용성의 증대
Python
egoing.py
1 2 3 4 5 6 | def a(): return 'a'def b(): return 'b'def c(): return 'c' |
4_1.py
1 2 | import egoingprint(egoing.a()) |
1 | a |
4_2.py
1 2 | import egoingprint(egoing.a()) |
1 | a |
로그인 에플리케이션
Python

5.py
1 2 3 4 5 6 | import authinput_id = input("아이디를 입력해주세요.\n")if auth.login(input_id): print('Hello, '+input_id)else: print('Who are you?') |
Ruby
