We have provided a list of tuples called state_capitals. The first item in every tuple is the name of a US state and the second item in that tuple is the capital of that state. Write code that converts this data structure into a dictionary where the keys are state names and the values are state capitals. Assign the result to the variables capitals_dict. state_capitals = [ ('Michigan', 'Lansing'), ('Massachusetts', 'Boston'), ('Pennsylvania', 'Harrisburg'), ('New York', 'Albany') ]

The solution code is written in Python:

state_capitals = [ ('Michigan', 'Lansing'), ('Massachusetts', 'Boston'), ('Pennsylvania', 'Harrisburg'), ('New York', 'Albany') ] capitals_dict = {} for x in state_capitals: capitals_dict[x[0]] = x[1] print (capitals_dict)

Explanation:

Firstly, we create a variable capitals_dict and initialize it with a empty dictionary (Line 3).

Next, we use the for-loop to traverse through each tuple item in the state_capitals list (Line 5). Within the loop, we use the syntax x[0] to take out the first item (state) from the tuple and use it as the key capitals_dict[x[0]]. We use the syntax x[1] to take out the second item (capital) from the tuple and set it as the value of the dictionary (capitals_dict[x[0]].). (Line 6)

When finishing the loop, we can print the dictionary (Line 7) and the output is as follows:

{'Michigan': 'Lansing', 'Massachusetts': 'Boston', 'Pennsylvania': 'Harrisburg', 'New York': 'Albany'}
