When it is required to convert a matrix to a dictionary value list, a simple dictionary comprehension can be used.
Example
Below is a demonstration of the same
my_list = [[71, 26, 35], [65, 56, 37], [89, 96, 99]]
print("The list is :")
print(my_list)
my_result = {my_index + 1 : my_list[my_index] for my_index in range(len(my_list))}
print("The result is:")
print(my_result)Output
The list is :
[[71, 26, 35], [65, 56, 37], [89, 96, 99]]
The result is:
{1: [71, 26, 35], 2: [65, 56, 37], 3: [89, 96, 99]}Explanation
A list of list is defined and is displayed on the console.
A dictionary comprehension is used to iterate over the list, and check specific elements of the list using list slicing and indexing.
This is converted to a dictionary and assigned to a variable.
This is displayed as output on the console.
