Sometimes, while working with Python Dictionaries, we can have a problem in which we need to convert dictionary list to nested records dictionary taking each index of dictionary list value and flattening it. This kind of problem can have application in many domains. discuss certain ways in which this task can be performed.
Python program that converts a dictionary value list to a dictionary list:
# Define a dictionary with list values dict_with_list = {'key1': [1, 2, 3], 'key2': [4, 5, 6], 'key3': [7, 8, 9]} # Create an empty list to store the dictionary list dict_list = [] # Iterate over the dictionary key-value pairs for key, value_list in dict_with_list.items(): # Create a new dictionary with the key and value list new_dict = {'key': key, 'values': value_list} # Append the new dictionary to the dictionary list dict_list.append(new_dict) # Print the resulting dictionary list print(dict_list
This program defines a dictionary dict_with_list
with keys that each have a list of values. It then creates an empty list dict_list
to store the resulting dictionary list.
The program then iterates over each key-value pair in dict_with_list
, and creates a new dictionary with the key and value list. This new dictionary is then appended to dict_list
.
Finally, the resulting dictionary list is printed to the console. This dictionary list contains one dictionary for each key in dict_with_list
, with the key as the key
field in the dictionary, and the list of values as the values
field in the dictionary.
