python 列表,字典,元组,字符串,QuerySet之间的相互转换

1. 列表转换成字典list1 = ['key1','key2','key3']list2 = ['value1','value2']

dict1 = zip(list1,list2) # dict(dict1)={'key1':'value1','key2':'value2'}

2.字典转换为列表dict1 = {'key1':'value1','key2':'value2'}list1 = list(dict1) #list1 = ['key1','key2']list1 = list(dict1.values()) #list1 = ['value1','value2']

3.列表转换为元组list2 = ['value1','value2']data_tuple = tuple(list2)

4.元组转换为列表tuple1 = (1,2,3)list1 = list(tuple1)

5.列表转换为字符串list1 = ['key1','key2']','.join(list1) key1,key2

6.字符串转换为列表str_date ='12345'list1 = list(str_date) #[1,2,3,4,5]

7.QuerySet转换为列表list1 = Object.objects.values()list1 = list(QuerySet)

8.字典转换为元组dict1 = {'key1':'value1','key2':'value2'}tuple(dict1) # ('key1'，'key2')

9.QuerySet转换为字典model_to_dict(QuerySet)Object.objects.get(id=id).__dict__
