Is your keyboard layout set correctly?

I would suppose so, cause I used nmcli d WiFi connect SSID password PASSWORD, and the PASSWORD is displayed correctly.

Does the SSID or password have a , or weird character?

My password is alphanumeric, so that shouldn’t be the issue. My SSID is alphanumeric + (), but I don’t think that’s the issue either cause I cannot connect to my password protected hotspot that is only alphanumeric.

Yea I tried, same issue

I think there’s a spectrum here, and I’ll clarify the stances.

The spectrum ranges from “Data shouldn’t cause the function to do (something wildly) different” to “It should be allowed, even to the point of variable returns”

I think you stand on the former while I stand on the latter. Correct me if I’m wrong though, but that’s the vibe I’m getting from the tone in your example.

Data shouldn’t drive the program in this way.

Suppose we have a function that calculates a price of an object. I feel it is agreeable for us to have compute_price(with_discount: bool), over compute_price_with_discount() + compute_price_without_discount()

You’ve basically spelled:

I feel your point your making in the example is a bit exaggerated. Again, coming back to my above example, I don’t think we would construe it as compute_price('with_discount').

Maybe this is bandwagoning, but one of the reason for my stance is that there are quite a few examples of variable returns.

eg:

• getattr may return a different type base on the key given
• quite a few functions in numpy returns different things based on flags. SVD will return S if compute_uv=False and S,U,V otherwise

I thought about it, but it isn’t as expressive as I wished.

Meaning if I do

a = foo(return_more=True)
or
a, b = foo(return_more=False)

it doesn’t catch these errors for me.

In comparison, the other suggested solution does catch these.

yea, this is pretty close to what I’m looking for.

The only missing piece is the ability to define the overload methods on the bool

something like

@overload
def foo(return_more: True) -> (Data, Data)

@overload
def foo(return_more: False) -> Data

But I don’t think such constructs are possible? I know it is possible in Typescript to define the types using constants, but I don’t suppose Python allows for this?

EDIT: At first, when I tried the above, the typechecker said Literal[True] was not expected and I thought it was not possible. But after experimenting some, I figured out that it is actually possible. Added my solution to the OP

Thanks for the tip!

but from a practical perspective, let’s say you retrieve an object and can either return a subset of its fields as your API. Doesn’t it make sense to re-use the same function, but change what fields are returned?

I’m specifically talking about the narrow use-case where your API returns either A or B of the fields, and won’t extend it in the future

The alternative is to either duplicate the function, or extract it out which seems a bit overkill if it is only 2 different type of functions.
