lambda 赋值方式

Question

In my python code, I want to assign the "name" value into " request_body " based on the input, something as if:

def make_api_call(context, name, ...):
    api_name = f"<my_API_Call_URL_here>"
    request_body= {}
    request_body["name"] = lambda name:  "" if name == "BLANK" else name
    ...
    context.base.execution_call(context, api_name, request_body, "post")

    

Is that the correct way in lambda to have the string value assigned to request_body["name"] ?

Somehow, when I to make the api call in the end, I have got such error message:

TypeError: Object of type function is not JSON serializable

Answer 1

lambda is an alternative way to create a small function and there's no need for it in your case. You should use something like:

request_body["name"] = "" if name == "BLANK" else name

You can't use a lambda to "assign a value" without calling it:

>>> a = lambda name: "" if name == "BLANK" else name
>>> type(a)
<class 'function'>

Answer 2

if you want your lambda that bad try this

test_name = lambda x:  "" if x == "BLANK" else x
request_body["name"] = test_name(name)
