You can convert a Python list to a dictionary using the dict.fromkeys() method, a dictionary comprehension, or the zip() method. The zip() method is useful if you want to merge two lists into a dictionary. Let’s quickly summarize these methods: dict.fromkeys(): Used to create a dicti...
# 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...
Unlike sets, lists can contain duplicate values which can cause values when you need to convert them into a dictionary. To avoid errors from duplicate keys when converting a list to a dictionary, you can create a mechanism to handle the duplicate values. Take into consideration the following pr...
Convert Dict Values to List Python using List Comprehension Here, we will use list comprehension, which will use the same logic that we’ve used in the previous example, but the difference is that it will use the one-liner for loop, and in the list comprehension, there is no need to ap...
To convert a list of tuples into a dictionary in Python, use the dict() constructor with either the list comprehension approach or the map() method.

Example 2: Transform the Lists into a Dictionary with Dictionary ComprehensionIn this second example, we will make use of dictionary comprehension to convert the lists into a dictionary:my_dict = {keys[i]: values[i] for i in range(len(keys))} print(my_dict) # {'Name': 'Chioma', '...
dict_data = pythonconvert(string_data, 'dict') print(dict_data) # Output: {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'} III. Conversion of Lists: The pythonconvert function can also beused to convert lists to other types: 1. Converting a list to a string: list_da...
We used thelistclass to convert each row to a list. The last step is to call theDataFrame.to_dict()method to convert the resultingDataFrameto a dictionary. #GroupBy results to Dictionary of Lists using a dict comprehension You can also use adict comprehensionto convert the results of a Gro...
To convert a dictionary to a list of tuples using the zip() function, we will pass the list of keys and the list of values as input to the zip() function. We can obtain the list of keys using the keys() method. The keys() method, when invoked on a dictionary, returns a dict_...
