Hi I just started to try out Trie in Python. I have a code like this but when I get the output, I don't know how to convert it back to a normal list or dictionary.
Input:
TestDict = {0: {"ItemName" : "washing machine", "ItemStockLevel" : 15, "ItemCostPrice" : 129.21, "ItemSellingPrice" : 142.21},
1: {"ItemName": "french fries", "ItemStockLevel": 100, "ItemCostPrice": 21.51, "ItemSellingPrice": 41.77},
2: {"ItemName" : "magnum ice cream", "ItemStockLevel" : 30, "ItemCostPrice" : 57.32, "ItemSellingPrice" : 78.31}}
test = []
for key in TestDict:
test.append(TestDict[key]["ItemName"])
_end = '_end_'
def make_trie(list):
root = dict()
for word in list:
current_dict = root
for letter in word:
current_dict = current_dict.setdefault(letter, {})
current_dict[_end] = _end
return root
print(make_trie(test))
Output:
{'w': {'a': {'s': {'h': {'i': {'n': {'g': {' ': {'m': {'a': {'c': {'h': {'i': {'n': {'e': {'_end_': '_end_'}}}}}}}}}}}}}}}, 'f': {'r': {'e': {'n': {'c': {'h': {' ': {'f': {'r': {'i': {'e': {'s': {'_end_': '_end_'}}}}}}}}}}}}, 'm': {'a': {'g': {'n': {'u': {'m': {' ': {'i': {'c': {'e': {' ': {'c': {'r': {'e': {'a': {'m': {'_end_': '_end_'}}}}}}}}}}}}}}}}}
Want to get:
{"washing machine", "french fries", "magnum ice cream"}
using the Output above.
TestDict = {0: {"ItemName" : "washing machine", "ItemStockLevel" : 15, "ItemCostPrice" : 129.21, "ItemSellingPrice" : 142.21},
1: {"ItemName": "french fries", "ItemStockLevel": 100, "ItemCostPrice": 21.51, "ItemSellingPrice": 41.77},
2: {"ItemName" : "magnum ice cream", "ItemStockLevel" : 30, "ItemCostPrice" : 57.32, "ItemSellingPrice" : 78.31}}
test = []
for key in TestDict:
test.append(TestDict[key]["ItemName"])
_end = '_end_'
def make_trie(list):
root = []
for word in list:
root.append(word)
return root
print(set(make_trie(test)))
{'magnum ice cream', 'french fries', 'washing machine'}
