I'm trying to combine the values of two lists into single dictionary set but after combining dictionaries key and values are not arranged as origional order in list , it pairs with random key and values, so how can I combine them in order? See the input and output below:

data_ids = ['22630876', '22626950', '22624826', '22626159', '22616496', '22601480', '22611197', '22600498', '22605808', '22602601', '22602543', '22594071', '22595982', '22593725', '22591441', '22553315', '22584758']



tag_ids = ['WATCH - Stokes faces unpredictable balls', "'Bad position, but we're not out of it' - de Villiers", 'Who is Sandeep Lamichhane?', 'WATCH - All the action from the Super Over', "WATCH - Sammy's four-ball blitz", "Shubman Gill's red-hot run streak", 'Should bowlers start wearing helmets?', 'Keshav Maharaj could be key - Graeme Smith', "WATCH - Kevin Pietersen's match-winning 48", "'It was emotional walking off the pitch' - Stokes", "WATCH - India's gains from the South Africa tour", 'WATCH - Best of Kohli in South Africa', 'The Ashwin-Gibbs exchange: funny, or not?', "Mayank Agarwal's incredible run of domestic form", "'SA can't afford spicy pitches against Australia'", 'Ice Cricket: Legends play T20 in the Alps', 'Dhoni, Kohli and quirky on-field  chatter']


z = dict(zip(data_ids,tag_ids))

print(z)



{'22595982': 'The Ashwin-Gibbs exchange: funny, or not?', '22593725': "Mayank Agarwal's incredible run of domestic form", '22626159': 'WATCH - All the action from the Super Over', '22553315': 'Ice Cricket: Legends play T20 in the Alps', '22626950': "'Bad position, but we're not out of it' - de Villiers", '22624826': 'Who is Sandeep Lamichhane?', '22611197': 'Should bowlers start wearing helmets?', '22630876': 'WATCH - Stokes faces unpredictable balls', '22600498': 'Keshav Maharaj could be key - Graeme Smith', '22602601': "'It was emotional walking off the pitch' - Stokes", '22602543': "WATCH - India's gains from the South Africa tour", '22591441': "'SA can't afford spicy pitches against Australia'", '22601480': "Shubman Gill's red-hot run streak", '22594071': 'WATCH - Best of Kohli in South Africa', '22605808': "WATCH - Kevin Pietersen's match-winning 48", '22584758': 'Dhoni, Kohli and quirky on-field  chatter', '22616496': "WATCH - Sammy's four-ball blitz"}

as you can see the output of z starts with key value '22595982' but it should be '22630876', even same with values of dictionary, how can I do this, I searched for similar question but I didn't find any

Try this, I guess this will be your answer.

from collections import OrderedDict

d = OrderedDict(zip(data_ids, tag_ids))
for i, j in d.items():
    print(i)
    print(j)

Python, For this, simply declare a dictionary, and then run nested loop for both the lists and assign key and value pairs to from list values to dictionary. The more concise way to achieve the above method, dictionary comprehension method offers the faster and time-saving approach by reducing the lines to type. The basic method that can be applied to perform this task is the brute force method to achieve this. For this, simply declare a dictionary, and then run nested loop for both the lists and assign key and value pairs to from list values to dictionary.

You should never rely on order of elements when using the default dict even if it happens to match some expectation. There is a dedicated dictionary implementation that keeps the order of insertion, starting from 2.7:

class collections.OrderedDict([items])

Return an instance of a dict subclass, supporting the usual dict methods. An OrderedDict is a dict that remembers the order that keys were first inserted. If a new entry overwrites an existing entry, the original insertion position is left unchanged. Deleting an entry and reinserting it will move it to the end.

How to Convert Two Lists into a Dictionary in Python: Zip , There are three different ways of converting two lists into key:value pair dictionary​. #using dictionary comprehension to convert list into dictionary How do you append to a file? python-list · python-datatypes · python · python-functions · python-sequence-types · python-types · python-programming. With the three methods above, we should easily be able to convert two lists into a dictionary. column_names = ['id', 'color', 'style'] column_values = [1, 'red', 'bold'] # Convert two lists into a dictionary with zip and the dict constructor.

Example:

from collections import OrderedDict

d = OrderedDict()

d["1"] = 1
d["5"] = 5
d["2"] = 2
print(d) #OrderedDict([('1', 1), ('5', 5), ('2', 2)])

new_d = dict(d)

print(d) #{'1': 1, '5': 5, '2': 2}

How do you convert two lists into a dictionary?, Write a Python program to map two lists into a dictionary. Sample Solution:- Python Code: keys = ['red', 'green', 'blue'] values = ['#FF0000','#  Following conversions from list to dictionary will be covered here, Convert a List to Dictionary with same values; Convert List items as keys in dictionary with enumerated value; Convert two lists to dictionary; Convert a list of tuples to dictionary; Convert a List to Dictionary with same values.

Since lists are an ordered collection, this works for me:

mydict = dict(zip(list1, list2))

Python Program to Map two lists into a Dictionary, Second, you can pop the id so you don't have to know the other keys in the various dictionaries: To mitigate that, we can start with an empty dictionary, update with for dictionary in sequence: result[dictionary['id']].update(dictionary) If you want to merge lists of dicts, you don't have to reinvent the wheel  In this article, we will discuss few ways of merging dictionaries. Using the method update() By using the method update() in Python, one list can be merged into another. But in this, the second list is merged into the first list and no new list is created. It returns None. Example:

Merge two list of dicts with same key, The program takes two lists and maps two lists into a dictionary. + ":")) values.​append(element) d=dict(zip(keys,values)) print("The dictionary is:") print(d). In this article we will discuss different ways to merge two or more dictionaries. Also, handle scenarios where we need to keep the values of common keys instead of overwriting them. Merge two dictionaries using dict.update() In Python, the Dictionary class provides a function update() i.e.

Python Program to Map Two Lists into a Dictionary, To repeat what others have said - the pythonic way to combine two lists into a dictionary is : [code]new_dict = dict(zip(keys, values)) [/code]How does this work ? Our code has two dictionaries: user and defaults. We want to merge these two dictionaries into a new dictionary called context. We have some requirements: user values should override defaults values in cases of duplicate keys; keys in defaults and user may be any valid keys; the values in defaults and user can be anything

Comments
  • Use Python 3.7.
  • doesn't it work with 3.5.2? @wim
  • They will be paired up correctly, and that's all that matters. If you need to preserve original ordering, then you've got the wrong data structure here.
  • what does json.dumps() do?
  • Just print the output of variable d you will get the answer as OrderedDict not as dict in json format, so just converted to plain json using json.dumps
  • Yeah but the output dstring is a string, I can't render this on the template , I get jinja2.exceptions.UndefinedError: 'str object' has no attribute 'items' error
  • can I fix this? @amazingthingsaround
  • @steve yes.. just moment .. let me try t.
