Python—数据类型之字典(Dict)

其它数据类型转成字典

arr1 = ['jack', 'rose', 'marry']
arr2 = [68, 85, 66]
dict1 = dict(zip(arr1, arr2))
print(dict1)      # {'rose': 85, 'marry': 66, 'jack': 68}

dict2 = dict((('a',2), ('b',4)))
print(dict2)      # {'a': 2, 'b': 4}
 
dict3 = dict((['a',2], ['b',4]))
print(dict3)      # {'a': 2, 'b': 4}
 
dict4 = dict([('a',2), ('b',4)])
print(dict4)      # {'a': 2, 'b': 4}
 
dict5 = dict([['a',2], ['b',4]])
print(dict5)      # {'a': 2, 'b': 4}
