I am trying to create an HTML selected menu. I have the following python data structure:
categories = [
['Sports & Outdoors', 'Outdoor Recreation', 'Skates, Skateboards & Scooters']
['Toys & Games', 'Learning & Education', 'Science Kits & Toys']
['Toys & Games', 'Arts & Crafts', 'Craft Kits']
['Toys & Games', 'Arts & Crafts', 'Drawing & Painting Supplies', 'Crayons']
['Home & Kitchen', 'Home Décor', 'Window Treatments', 'Window Stickers & Films']
]
However to get this to work with the HTML/JQuery menu, I need to change the above data structure to this:
categories = [
{
"name": 'Sports & Outdoors',
"subcategory": [
{
"name": 'Outdoor Recreation',
"subcategory": [
{
"name": 'Skates, Skateboards & Scooters',
"last": True
}
]
}
]
},
{
"name": 'Toys & Games',
"subcategory": [
{
"name": 'Learning & Education',
"subcategory": [
{
"name": 'Science Kits & Toys',
"last": True
}
]
},
{
"name": 'Arts & Crafts',
"subcategory": [
{
"name": 'Craft Kits',
"last": True
},
{
"name": 'Drawing & Painting Supplies',
"subcategory": [
{
"name": 'Crayons',
"last": True
}
]
}
]
},
]
},
{
"name": 'Home & Kitchen',
"subcategory": [
{
"name": 'Home Décor',
"subcategory": [
{
"name": 'Window Treatments',
"subcategory": [
{
"name": 'Window Stickers & Films',
"last": True
}
]
}
]
}
]
}
]
I can’t get to wrap my head around it. Any help is appreciated. How can I convert the python list of list, to a list of dictionary items as shown above, at the same time doing the grouping? If possible at the end of the tree, indicating with a "last": True.
>Solution :
try this:
categories = [
['Sports & Outdoors', 'Outdoor Recreation', 'Skates, Skateboards & Scooters'],
['Toys & Games', 'Learning & Education', 'Science Kits & Toys'],
['Toys & Games', 'Arts & Crafts', 'Craft Kits'],
['Toys & Games', 'Arts & Crafts', 'Drawing & Painting Supplies', 'Crayons'],
['Home & Kitchen', 'Home Decor', 'Window Treatments', 'Window Stickers & Films']
]
new_categories = []
for category in categories:
existing_category = next((c for c in new_categories if c["name"] == category[0]), None)
if existing_category:
new_category = existing_category
else:
new_category = {"name": category[0], "subcategory": []}
new_categories.append(new_category)
last_subcategory = new_category
for subcategory in category[1:]:
existing_subcategory = next((c for c in last_subcategory["subcategory"] if c["name"] == subcategory), None)
if existing_subcategory:
new_subcategory = existing_subcategory
else:
new_subcategory = {"name": subcategory, "subcategory": []}
last_subcategory["subcategory"].append(new_subcategory)
last_subcategory = new_subcategory
last_subcategory["last"] = True
print(new_categories)
