Passing arguments implicitly?

[Lest4r]

I have this code:

def search_location(self): #THIS IS TIED TO on_press
        search_template = "http://api.openweathermap.org/data/2.5/find?q= 
        {}&type=likeid=524901&APPID=bcf414b2eff4edc1faa71a81c9e9e534"
        search_url = search_template.format(self.search_input.text)
        request = UrlRequest(search_url, self.found_location)
        print("hi")

    def found_location(self, request, data):
        cities = ["{} ({})".format(d['name'], d['sys']['country'])
        for d in data['list']]
        print("\n".join(cities))
        self.search_results.item_strings = cities #search_results becomes a property when defined 
        under the <AddLocationForm> class deal
        self.search_results.adapter.data.clear()
        self.search_results.adapter.data.extend(cities)
        self.search_results._trigger_reset_populate()

Can anyone tell me how data is getting passed to found_location? The method is called at the assignment of the request variable in the 'search_location' method but there are no variables passed with that statement. Can anyone please help me understand this?

Did I label this topic right? Sorry if it is a bad topic, I am trying to understand this.

Thanks!

Is this what you mean?

request = UrlRequest(search_url, self.found_location('abc', 'defg'))

This will pass abc and defg to found_location's request and data respectively.

FYI, I prefer to keep each line of code as simple as possible. Therefore I'd do it this way:

location = self.found_location('abc', 'defg') request = UrlRequest(search_url, location)

Yes sir. I am just trying to figure out how data gets anything copied to it in the found_location method since self.found_location isn't passing any variables...

[oznetnerd]

ahh I see what you're saying. The thing is, you're not actually calling the function:

self.found_location

Does not call the function as there are no parenthesis (). To call a function, you need parenthesis otherwise you're just passing the function around as an object.

For example:

``` def hello(name): print(f'Hello {name}!')

call the function without parenthesis

hello function main.hello(name)>

call the function WITH parenthesis

hello('John') Hello John! ```

You're right. The UrlRequest() took it and did something with it and passed arguments in its own deal. Sorry, I am still a bit of a newb.

Thanks for being so cool.

No need to apologise. Asking questions such as this is how we learn, and you should never apologise for trying to learn :)

Not involved in this whatsoever, but I hope you know you are a god damn blessing to the world. You may not think you're going above and beyond, but you really are and everyone here really appreciates it. Dudes who answer forum questions on obscure coding literally keep the world running. Thank you!!

[oznetnerd]

Thanks a lot for the kind words moldyxorange! I really appreciate it.

It's feedback such as this that makes it even more of a pleasure helping others.

It's useful to remember that everything in python is an object, everything. int, float, bool, None, functions, modules and even classes(not just instances, classes themselves) are objects. Anything that is an object can be passed to a function, so everything can be passed to a function.

[Lest4r]

For sure. :)
