# Quick examples of converting a list into a dictionary # Example 1: Create a dictionary using a dictionary comprehension my_list = ["Python", "Pandas", "Spark", "PySpark"] my_dict = { item : "Course" for item in my_list } print(my_dict) # Example 2: Convert list to dict using...
Write a Python program to convert a given list of dictionaries into a list of values corresponding to the specified key. Use a list comprehension and dict.get() to get the value of key for each dictionary in lst. Sample Solution: Python Code: # Define a function 'pluck' that takes a l...
Here we iterate over all dictonaries in list. For every dictionary we iterate over its .items() and extract the key and value and then we construct a tuple for that with (key,)+val. Whether the values are strings or not is irrelevant: the list comprehension simply copies the reference ...
Dictionary comprehension: Creates a new dictionary from an existing list. You can specify different values for each key in the dictionary. Dictionary comprehensions are similar toPython list comprehensionsin structure. zip(): Converts two or more lists into a list of tuples. You can use the dic...

As seen, we have two lists defined under the names: keys and values. Now let’s continue with the first example of the tutorial! Example 1: Transform the Lists into a Dictionary with dict() & zip() Functions In this example, we will use Python’sdict()function to convert the lists ...
values():Make sure that you are using this method for the dictionary only; otherwise, it will give an error. list() constructor: It will convert the extracted dictionary values to the list. Here’s an example that shows how toconvert dict_values to list in Pythonusingdict.values()method ...
list3 = ["apple", "mango", 16, "cherry", 3.4] Python Dictionary Dictionaries are Python's other built-in data type and it is also known as an associative array. A dictionary consists of a collection of key-value pairs. Each key-value pair maps the key to its associated value. Data...
tuple_data = pythonconvert(list_data, 'tuple') print(tuple_data) # Output: (1, 2, 3, 4, 5) IV. Conversion of Dictionaries: The pythonconvert function can be handy when converting dictionaries to other types: 1. Converting a dictionary to a string: dict_data = {'key1': 'value1',...
print("The list of tuples is:", myList) Output: The Dictionary is: {1: 2, 3: 4, 5: 6, 7: 8} The list of tuples is: [(1, 2), (3, 4), (5, 6), (7, 8)] Instead of using the list() function, we can uselist comprehensionto convert the dict_items to a list as ...
