[英]How to read a txt file and create a dictionary with each key having list of values in python?
[英]How to read a txt file in python and output a dictionary with associating each word with a key outside txt file
我正在閱讀一個格式為 txt 的文件
apple, 1234, 156789086654, cat, John
orange, 7654, 8268249252745, dog, Smith
mango, 3467, 8328627427, cow, Alice
我有一個 key_fields 字典,將鍵與值類型相關聯
key_fields = { fruit : str
num : int
date : long
animal : str
name : str }
我想從 txt 文件和 key_fields 創建一個最終字典,其中 txt 文件中每一行的每個屬性都映射到這樣的 key_fields,並具有與 dict key_fields 匹配的適當類型的值字段 -
{ 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" }
例如,只有一個條目:
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(", "))}
