python的三種建立字典的方法

#建立乙個空字典

empty_dict =dict() 
print(empty_dict)
#用**kwargs可變引數傳入關鍵字建立字典
a = dict(one=1,two=2,three=3
) print(a)
#傳入可迭代物件
b = dict(zip(['
one','
two','
three
'],[1,2,3
]))print(list(zip([
'one
','two
','three
'],[1,2,3
])))
print(b)
#傳入可迭代物件 
c = dict([('
one', 1), ('
two', 2), ('
three
', 3
)])print(c)
c1 = dict([('
one', 1), ('
two', 2), ('
three
', 3),('
three
', 4),('
three
', 5
)])print(c1)#如果鍵有重複，其值為最後重複項的值。 
#傳入對映物件，字典建立字典  
d = dict() 
print(d) 
print(a == b == c ==d)
