How do i convert a list of strings into a list of dictionaries in python?

January 13, 2024

I’d like to convert a list of structurally similar strings into a list of dictionaries.

Example list of strings:

list_of_strings = [
'ID payment_method email issue_date payment_date amount currency',
'ID payment_method email issue_date payment_date amount currency',
'ID payment_method email issue_date payment_date amount currency',
...
]

Each snippet of information is sperated by a whitespace inside the strings themselves.

Desired output:

resulting_list_of_dicts = [
dict_1 = {"ID": "id1", "payment_method": "paymentmethod1", "e_mail": "email1", "payment_date": "paymentdate1", "amount": "amount1", "currency": "currecny1"},
dict_2 = {"ID": "id2", "payment_method": "paymentmethod2", "e_mail": "email1", "payment_date": "paymentdate2", "amount": "amount2", "currency": "currecny2"},
...
]

I’ve tried using the string split function, by I am running into trouble when trying to append the sub strings to a dict.

>Solution :

Loop over each line in the string list.

Use split() to get each separate part.

Build a new dictionary from those parts and append it to another list.

list_of_dicts = [] 
for s in list_of_strings:
    parts = s.split()
    list_of_dicts.append({
        'id': parts[0],
        'payment_method': parts[1],
        ... and so on
    })
