Step 4 And If the integer number is in the nested dictionary so that call the above created function recursively and add the returned value to the sum. Step 5 End algorithm by returning the value of sum.Example# Function to get the summation of values def summation_values(the_dictionary):...
In the code above, we initialize two lists, listOne and listTwo. We then employ a list comprehension with nested for loops to iterate through all possible combinations of elements from the two lists. Next, the condition if a != b ensures that we exclude pairs where the elements from both...
