python之从列表或元组创建字典

利用推导式创建字典

k = ['key1', 'key2', 'key3']
v = ['value1', "value","value3"]
dic = { i:v[k.index(i)] for i in k }
print(dic)

根据对应的序列元素直接转化为字典

D=[('key1','value1'),['key2','value2']]
D=dict(D)
print(D)

将两个字典合并

k = {'key1':'value1', 'key2':"value2"}
v = {'key3':"value3"}
dic = dict(k,**v)
print(dic)
