请教一个 Python 问题（应该是个比较简单的问题）

def test(name){
    if name = 'a':
	SqlModele.objects.filter(condition1='xxx').first()
    elif name = 'b':
     	SqlModele.objects.filter(condition2='xxx').first()
    elif name = 'c':
     	SqlModele.objects.filter(condition3='xxx').first()
}

请问我如何把上文代码中的查询条件（ condition1 、condition2 、condition3 ）通过函数传参的形式传入方法呢？想要的效果是：

def test(name){

    if name = 'a':
	query_condition=condition1
    elif name = 'b':
    	query_condition=condition2
    elif name = 'c':
    	query_condition=condition3
        
    SqlModele.objects.filter(query_condition='xxx').first()
}

name

elif

lter

xxx'

关键词 kwargs

举例：

d = {"k": 1}

def f(k):
print(k)

f(**d)

condition = {'a': condition1, 'b': condition2, 'c': codition3}

def test(name){

query_condition=condition[name]

SqlModele.objects.filter(query_condition=query_condition).first()
}

不是，我回完了才看出来，你这 python 的函数定义怎么有大括号啊。。。。。。。。。。。。
