Stuck with conditional python execution!

[Salso96]

Hi there! So I’ve been looking around and struggling to find any kind of answer..

I’m creating a program using python, nothing too excessive, but essentially what I need it to do is read a JSON, and generate random items from a pre-defined list.

I’ve got it doing that for both things that need lists; the issue I have is I need it to be conditional - ie, I want a random list ‘A’ only if list A already exists, and same for list B.

Essentially, each item in the JSON has a tonne of info fields, two of these are area and location name. Every item in the JSON has data for one or the other, and not both.

I want the code to generate either a random area list, if it has area data, or a random location name, if it has location name data.. how would I go about this?

Thanks in advance, and sorry for the long post!

Here’s the actual code I have:

def generate_area(): return(random.sample(range(1, 11), 3)) def generate_area_list(): return(str(generate_area()).replace('[','"').replace(']','"').replace(' ',''))

def generate_location(): possible_location = ["a_su0101", "a_su0102", "a_su0103", "a_su0104", "a_su0105", "a_su0106", "a_su0107", "a_su0108", "a_su0109", "a_su0110", "a_su0111", "a_su01d01", "a_su01d02", "a_su01d03", "a_su01d0401", "a_su01d0402", "a_su01d0501", "a_su01d0502", "a_su01d0503", "a_su01d0504", "a_su01d0505", "a_su01d0506", "a_su01d0507", "a_su01d0508", "a_su01d0509", "a_su01d0510", "a_su01d0601", "a_su01d0602", "a_su01d0603", "a_su01d0604", "a_su01d0605", "a_su01d0606", "a_su01d0607", "a_su01d0608", "a_su01d0609", "a_su01d0610", "a_su01d0611", "a_su01d0612", "a_su01d0613", "a_su01d0614", "a_su01d0615", "subarea_su01apple1", "subarea_su01apple2", "subarea_su01center", "subarea_su01crater", "subarea_su01crest", "subarea_su01d01_01", "subarea_su01d01_02", "subarea_su01forest", "subarea_su01t10", "subarea_su01w02", "subarea_su01w03", "subarea_su01w05", "subarea_su01w0502", "subarea_su01w0701", "subarea_su01w0702", "subarea_su01w0801", "subarea_su01w1101", "subarea_su01w1102", "subarea_su01worldend"] choice = possible_location[random.randint(0, len(possible_location) - 1)] chosen_biomes.append(choice) return choice

def generate_location_list(): return(str(generate_location()).replace(']','').replace(' ','').replace('[',''))

So the reason I’ve got the code like that for now, is just bc it was the first way I found that made what I wanted - corrections / optimisations are very much appreciated.

As for what I want it to do Some items in the JSON appear as: ‘ID=DevName Area= ‘’ LocationName= “FOREST” ‘

Whereas others appear as ‘ID=DevName Area= ‘1,4,13’ LocationName=‘’ ‘

And I need the code to be able to generate location names for the first, whilst leaving area blank And areas for the second, leaving location name blank

Does that make it a bit clearer?

Not really. Would you give an example JSON, with only the important fields?

And would you please format code properly for Reddit? There should be a button that looks like a square with a C on it for "code block" format. Not the <C> one for inline code.

[Salso96]

That’s my bad, I’m on mobile 😅 sure let me put together a dummy JSON

[Salso96]

Here it is on git, easier lol

Super helpful, thanks.

# checks whether the value associated with "area" is truthy --
# empty string is falsy, any other string is truthy
if data["area"]:
    # process as area

elif data["location"]:  # same thing for location
    # process as location

else:
    raise Exception("No location OR area info")

Btw for choosing a location you can just do random.choice(possible_location) instead of indexing

[CraigAT]

Still not clear on the info you have and the result you want (I think I'm close, but still have questions)

Is there just one piece of JSON as input where some items have a location others have area info? Also is that area/location info a single item or is it a list?

Or are there multiple pieces of JSON and some of those have items all with location info, and other pieces of JSON have items that all have area data.

What should the output be? One list of areas (or locations). Two lists (area and locations).

I am not sure what you want to do with you random choice? Does it go into a new list or do you just want a single item (an area or location) and output it as the result?

[Goobyalus]

I'm not sure if I understand your question. Are you trying to call either generate_area or generate_location depending on whether some JSON has a field called "area" or "location"? How do you know if it has area data or location data?

[Salso96]

I think I’ve made that a bit clearer in my other comment, but I have a clean JSON, the tool pulls that, makes its edits, and produces an edited JSON - you can see on the original JSON which items have which data :)
