I'm reading a txt file which is of form
apple, 1234, 156789086654, cat, John
orange, 7654, 8268249252745, dog, Smith
mango, 3467, 8328627427, cow, Alice
I have a dictionary of key_fields associating keys with value type
key_fields = { fruit : str
num : int
date : long
animal : str
name : str }
I want to create a final dictionary from txt file and key_fields, where each attribute from each line in txt file is mapped to the key_fields like this, with appropriate type of value fields matching the dict key_fields -
{ fruit: "apple", num : 1234, date : 156789086654, animal : "cat", name : "John" }
{ fruit: "orange", num: 7654, date: 8268249252745, animal : "dog", name : "Smith"}
{ fruit: "mango", num: 3467, date : 8328627427, animal: "cow", name: "Alice" }
As an example with just one entry:
line_1 = "apple, 1234, 156789086654, cat, John"
key_fields = {
"fruit": str,
"num": int,
"date": int,
"animal": str,
"name": str
}
result_dict = {key: builder(data) for ((key, builder), data) in zip(key_fields.items(), line_1.split(", "))}
