"파이썬 입문"의 두 판 사이의 차이

3.1.1 생성[편집]

>>> names = [ ]
>>> names = [‘a’, ‘b’, ‘c’, ‘d, ‘e’]

3.1.2 len(s)[편집]

>>> names = [‘a’, ‘b’, ‘c’, ‘d, ‘e’]
>>> len(names)
5

3.1.3 indexing[편집]

>>> names = [‘a’, ‘b’, ‘c’, ‘d, ‘e’]
>>> names[0]
‘a’
>>> names[1]
‘b’

3.1.4 append[편집]

>>> names = [‘a’, ‘b’,’c’]
>>> names.append(‘d’)
>>> names
[‘a’, ‘b’, ‘c’, ‘d’]

3.1.5 insert[편집]

>>> names = [‘a’, ‘b’, ‘c’]
>>> names.insert(1, ‘e’)
>>> names
[‘a’, ‘e’, ‘b’, ‘c’]

3.1.6 comprehension[편집]

• 컴프리핸션: 리스트를 한줄의 코드로 쉽게 만들때 사용

>>> data = [3, 4, 5]
>>> float_data = [float(d) for d in data]

3.2.1 생성[편집]

>>> names = (‘a’, ‘b’, ‘c’, ‘d, ‘e’)

3.2.2 len(s)[편집]

>>> names = (‘a’, ‘b’, ‘c’, ‘d, ‘e’)
>>> len(names)
5

3.2.3 indexing[편집]

>>> names = (‘a’, ‘b’, ‘c’, ‘d, ‘e’)
>>> names[0]
‘a’
>>> names[1]
‘b’

3.3.1 생성[편집]

>>> cur_price = { }

==== insert	====

>>> cur_price[‘samsung’] = 10000
>>> cur_price
{‘samsung’: 10000}

==== indexing	====

>>> cur_price[‘samsung’]
>>> 10000

==== delete	====

>>> del cur_price[‘samsung’]
>>> cur_price{}

==== key, value	====

>>> cur_price.keys()
dict_keys([‘samsung’])
>>> cur_price.values()
dict_values([10000])
