### set

data_set = {10, 20, "파이썬", "파이썬"}

print("{0} {1}".format(type(data_set), data_set))

data_set = set(range(10,21,2))
print("{0} {1}".format(type(data_set), data_set))

data_str = "Better Tommorrow"
data_set = set(data_str)
print("{0} {1}".format(type(data_set), data_set))

### 집합 

data_set1 = {1, 2, 2, 3, 4, 4, 5, 6, 7, 7, 7, 11}
data_set2 = {2, 3, 5, 9, 11, 12, 15]

print("{0} & {1} = {2}".format(data_set1, data_set2, data_set1 & data_set2))
print("{0} | {1} = {2}".format(data_set1, data_set2, data_set1 | data_set2))
print("{0} - {1} = {2}".format(data_set1, data_set2, data_set1 - data_set2))

print("{0}.intersection({1}) = {2}".format(data_set1, data_set2, data_set1.intersection(data_set2)))
print("{0}.union({1}) = {2}".format(data_set1, data_set2, data_set1.union(data_set2)))
print("{0}.difference({1}) = {2}".format(data_set1, data_set2, data_set1.difference(data_set2)))

### set 활용하기

data_set1 = {1, 2, 2, 3, 4, 4, 5, 6, 7, 7, 7, 11}0

data_set2 = {x for x in data_set1}
print("data_set2: {0} {1}".format(type(data_set2), data_set2))

data_set3 = {x for x in data_set1 if item %  2 == 1}
print("data_set3: {0} {1}".format(type(data_set3), data_set3))

data_set4 = {x for x in data_set1 if item % 2 == 0 }
print("data_set4: {0} {1}".format(type(data_set4), data_set4))

data_set5 = {x * y for x in data_set1 if x % 2 == 1
					for y in data_set1 if y %2 == 0}
print("data_set5: {0} {1}".format(type(data_set5), data_set5))

def inputspilt():
    inputdata = list(input().split(', '))
    return inputdata

print(sorted(inputspilt()))

위처럼 하면 알아서 정렬이 된다 

def inputspilt():
    inputdata = list(input().split(', '))
    return inputdata

def prettyprint(list):
    prettystr = ""
    for i in list:
        prettystr += "%s, "%i
    print(prettystr[:-2])
    return


result = sorted(inputspilt())
prettyprint(result)

그리고 출력을 이쁘게 하려면 이렇게 수정

dicBase = [[id('가'), id('깋')], [id('나'),id('닣')],[id('다'),id('딯')],[id('라'),id('맇')],[id('마'),id('밓')],[id('바'),id('빟')],[id('사'),id('싷')],[id('아'),id('잏')],[id('자'),id('짛')],[id('차'),id('칳')],[id('카'),id('킿')],[id('타'),id('팋')],[id('파'),id('핗')],[id('하'),id('힣')]]
print(dicBase)

뽑아쓰는 방법

print(dicBase[0][0])
print(dicBase[0][1])

a = id(input())
if dicBase[0][0]>=a>=dicBase[0][1]:
	print("ㄱ임")

### tuple()

data_tuple = (10,21.5, "파이썬:, True)

print("{0} {1}".format(type(data_tuple), data_tuple))

### tuple()

data_tuple = [10, 20, 30, 40, 50]

print("data_tuple: {0}".format(data_tuple))


print("data_tuple[0]: {0}".format(data_tuple[0]))

print("data_tuple[3]: {0}".format(data_tuple[3]))
print("data_tuple[4]: {0}".format(data_tuple[4]))

### 학점 구조 만들기

# -*- coding: utf-8 -*-

# 학점.py

scores = []

count = int(input("총 학생 수를 입력하세요: "))

for i in range(1, count + 1):
	score = []

    score.append(eng)
    scores.append(score)
    
for i, score inenumerate(socres):
	total = 0 
    for s in score:
    	total += s
    print("학생{0} => 총점: {1}, 평균: {2:0.2F}".format(i, total, total / len(score)))
