python数据结构转换（关于列表转为字典的两个小方法）-持续更

1、现在有两个列表，list1 = ['key1','key2','key3']和list2 = ['1','2','3']，把他们转为这样的字典：{'key1':'1','key2':'2','key3':'3'}

list1= ['key1','key2','key3']

list2= ['1','2','3']

new_dict1=dict(zip(list1,list2))

print(new_dict1)

2，将嵌套列表转为字典，有两种方法，

new_list=[['key1','value1'],['key2','value2'],['key3','value3']]

#方法1

new_dict2=dict(new_list)

print(new_dict2)

#方法2

new_dict201={}

for iin new_list:

    new_dict201[i[0]]=i[1]

print(new_dict201)
