sort vs sorted

거의 같다, 다만 sorted는 새로운 리스트를 만들 때 사용.

a = ["a", "d", "z", "D", "H"]
b = ['blue', 'yellow', 'red', 'Green', 'Orange']
   
a.sort(key=str.lower)
b2 = sorted(b, reverse=True, key=str.lower)
   
print(a)
print(b2)

['a', 'd', 'D', 'H', 'z']
['yellow', 'red', 'Orange', 'Green', 'blue']

dict(keys, values, items, sorted)

countries = {"KOREA":"SEOUL", "USA":"DC", "CHINA":"BEIJING"}

print(countries.keys())   #key들만 추출
print(countries.values())   #value 들만 추출
print(countries.items())    #key-value추출

>>> countries = {"KOR":"seoul", "GERMANY":"berlin", "FRANCE":"paris"}
>>> a = sorted(countries)
>>> a
['FRANCE', 'GERMANY', 'KOR']

 a = sorted(countries.items())
>>> a
[('FRANCE', 'paris'), ('GERMANY', 'berlin'), ('KOR', 'seoul')]

>>> a = sorted(countries.items(), reverse=True)
>>> a
[('KOR', 'seoul'), ('GERMANY', 'berlin'), ('FRANCE', 'paris')]

>>> def f1(x):
...     return x[0]
>>> def f2(x):
...     return x[1]

>>> a = sorted(countries.items(), key=f2)
>>> a
[('GERMANY', 'berlin'), ('FRANCE', 'paris'), ('KOR', 'seoul')]

>>> a = sorted(countries.items(), key=f1, reverse=True)
>>> a
[('KOR', 'seoul'), ('GERMANY', 'berlin'), ('FRANCE', 'paris')]
