I am trying to 'destructure' a dictionary and associate values with variables names after its keys. Something like

params = {'a':1,'b':2}
a,b = params.values()

But since dictionaries are not ordered, there is no guarantee that params.values() will return values in the order of (a, b). Is there a nice way to do this?

我想调用带有字段名称过滤器的查询,在运行时我不知道...不确定如何构造变量名称......或者我可能已经累了.

field_name = funct()
locations = Locations.objects.filter(field_name__lte=arg1)

如果funct()返回name将等于

locations = Locations.objects.filter(name__lte=arg1)

不知道该怎么做......

在Python中可能具有以下内容:

>>> vars = {'a': 5}
>>> makevars(vars)
>>> print a
5

因此,makevars将字典转换为变量.(一般来说这叫什么？)
