Python Create a Dynamic Dictionary Using For Loop
Below are some examples by which we can create a dynamic dictionary using for loop in Python:
Dynamic Dictionary Using a Simple for Loop
This method assigns each key-value pair as iterates over the lists of keys and values, so dynamically creating a dictionary. It does this by using a simple for loop.
Python3
# Approach 1: Using a Simple For Loop keys = [ 'name' , 'age' , 'city' ] values = [ 'Rahul' , 25 , 'New York' ] dynamic_dict = {} for i in range ( len (keys)): dynamic_dict[keys[i]] = values[i] print (dynamic_dict) |
{'name': 'Rahul', 'age': 25, 'city': 'New York'}
Python Dynamic Dictionary Using zip() and for Loop
The for loop iterates over the pairs of matching entries from the keys and values lists that the zip() function couples, resulting in the creation of a dynamic dictionary.
Python3
# Approach 2: Using Zip and For Loop keys = [ 'name' , 'age' , 'city' ] values = [ 'Rahul' , 25 , 'New York' ] dynamic_dict = {} for key, value in zip (keys, values): dynamic_dict[key] = value print (dynamic_dict) |
{'name': 'Rahul', 'age': 25, 'city': 'New York'}
Create Dynamic Dictionary Using Dictionary Comprehension
We may iterate over the keys and indices at the same time by combining enumerate and dictionary comprehension to create the dynamic dictionary.
Python3
# Approach 3: Dictionary Comprehension with Enumerate keys = [ 'name' , 'age' , 'city' ] values = [ 'Rahul' , 25 , 'New York' ] dynamic_dict = {key: values[i] for i, key in enumerate (keys)} print (dynamic_dict) |
{'name': 'Rahul', 'age': 25, 'city': 'New York'}
Dynamic Dictionary Using Items() Method
By sending the view of dictionary key-value pairs that the items() function returns to the dict constructor, we are able to build a dynamic dictionary.
Python3
#Approach 4: Using Items() Method keys = [ 'name' , 'age' , 'city' ] values = [ 'Rahul' , 25 , 'New York' ] dynamic_dict = dict ( zip (keys, values)) print (dynamic_dict) |
{'name': 'Rahul', 'age': 25, 'city': 'New York'}
Python Dynamic Dictionary by Merging Dictionaries in a For Loop
We may combine key-value pairs into the dictionary dynamically by using the update() function inside of a for loop
Python3
# Approach 5: Merging Dictionaries in a For Loop keys = [ 'name' , 'age' , 'city' ] values = [ 'Rahul' , 25 , 'New York' ] dynamic_dict = {} for key, value in zip (keys, values): dynamic_dict.update({key: value}) print (dynamic_dict) |
{'name': 'Rahul', 'age': 25, 'city': 'New York'}
Create Dynamic Dictionary Python using for Loop
A for loop may be used to cycle over a collection of keys and values in Python to generate a dynamic dictionary. With this method, we may create dictionaries on the fly depending on specific requirements or information. In this article, we will see how to create a dynamic dictionary in Python using a for loop.
