pyth coding with correct indentation please 2.a.  Complete the following code to build the states dictionary.  The USPresidents.txt file has a number of lines of data, with each line containing two pieces of data: a two letter state abbreviation and the name of a president born in that state.  The dictionary keys should be the state abbreviation and the dictionary values should be a count of how many presidents were born in that state (this is just like one of your lab exercises).  Only build the one dictionary – don't build any lists, etc.   states = {} file = open("USPresidents.txt", "r") for line in file: 2b)  Iterate through the states dictionary to print the key and value for each item in the dictionary.
