Question

It's python. Please don't forget to print alpha-sorted states. Not random. Thank you

Build a second dictionary from the USPresidents.txt file described in the previous exercise. Each key will again be a state abbreviation, however, the value will be the count of presidents from that state.

Create a set of the ten most populous US states (CA, TX, FL, NY, IL, PA, OH, GA, NC, MI).

Then create a new set that represents a set of populous US states that have had presidents born in them (you should be able to do this with one line of code).

Print a count of this new set along with an alpha-sorted listing of these states and how many presidents have been born in them.

Example output:

8 of the 10 high population states have had presidents born in them:
CA 1
GA 1
IL 1
NC 2 
And so on...

And this is what i've done

import sys
import os
file = "C:/Users/USPresidents.txt"

USPDict=dict()
value=1

with open(file) as fp:
for line in fp:
s=line.split()
if s[0] in USPDict:
USPDict[s[0]]+=1
else:
USPDict[s[0]] =value
States={"CA","TX","FL","NY","IL","PA","OH","GA","NC","MI"}
PopulorStates=set()
sorted(PopulorStates)

for val in States:

if(val in USPDict):
PopulorStates.add(val)
print("\n",len(PopulorStates)," of the 10 high population states have had presidents born in them:")

for val in PopulorStates:
if(val in USPDict):
print(val," ",USPDict[val])

Answer 1

modify the file path accordingly

please drop a comment if there's a problem
