【Python知识】 list初始化

lst = [1, 2, 3, 4, 5]

>>> lst = [n for n in range(5, 10)]
>>> print(lst)
[5, 6, 7, 8, 9]

>>> lst = ['x' for n in range(5)]
>>> print(lst)
['x', 'x', 'x', 'x', 'x']
>>> lst = ['z']*5
>>> print(lst)
['z', 'z', 'z', 'z', 'z']
>>> lst = [0]*3
>>> print(lst)
[0, 0, 0]

字典：dic={'a':12, 'b':34}
集合：s = {1, 2, 3, 4}        
列表：li=[1, 2, 3, 3]
元组：tup=(1, 2, 3, 4)    #元组是不可更改的列表

from collections import OrderedDict

>>> OrderedDict([('b', 2), ('a', 1)])
