I thought I had a solution to the program, but it has produced errors only. Any help would be appreciated. The list of states and populations is also attached. I appreciate your time and help. Thank you

# Now we start to look at small programs. Do not be intimidated... this program looks

# long, it is not. What I have done is include a MOUNTAIN of comments, explaining each

# part as we go. So, read this like a book. Start here, and work your way down. Each

# section explains what it is doing, and indicates where you should add your code to

# complete the program. You will find three items you need to address below.

#

# Most programs in the real world do not have this many comments.

# In a way, that is unfortunate because more often we as programmers are

# improving or fixing bugs in an existing program, rather than starting

# from scratch. Good comments are worth their weight in gold

# because they help you get up to speed quickly, understand what was intended, and describe what

# each section of the program is accomplishing. We will build up our skill in reading other people's

# programs over time, and for this course, you'll get pretty good at reading my programs.

# Okay, here we go

# I am creating a couple of lists that you will work with later in the code. You do not need

# to build these, I will build them for you. The information in these two lists will be supplied from a

# file on your local disk. Here are the names of the two lists:

state_names = [] # a list of all the state names as strings

state_populations = [] # a matching list of those state's populations as integers

# This is one form of debugging a program. I've added some code that will display additional

# information when this variable is set to True. After you complete the steps below, consider

# coming back here and setting this variable to True and see what happens.

print_internal_details = False

# FIRST STEP: Edit the data input file path

# Last week's Digging Deeper worked with a few US states and their populations. This week, we are going to use

# all 50 states. It is too much to type in, so we will start to use the computer to do the work for us.

# The information for all 50 states and their populations is stored in a file.

# This first step tells Python where to find that file.

# The next line of code (starting with INPUT_FILE =) you'll need to edit. Python uses this string

# to find the file.

# Instructions: On your computer, you may need to use a file manager to see the full path of this file,

# then edit the text string inside the single quotes to match your system.

# Leave the leading lowercase r in place (this tells Python not to react to the symbols in the text)

#

# What you see below is on a Windows system... on a Mac this might look like

# r'/Users/john/Documents/CIS156/ch4_us_state_info.csv'

INPUT_FILE = r'C:\Users\john\Documents\CIS156\ch4_us_state_info.csv'

# We're starting to move toward programs with a bit more structure, but don't let that throw you.

# This week you'll be putting your code inside a function called main, which begins right below this comment.

def main():

print('ch4: us_states_v5.py')

print('This program works with more states and their populations')

print("Load data from this file:", INPUT_FILE) # quick check to see if the filename looks ok

get_all_states() # this loads the two lists

if print_internal_details:

print_all_states() # this displays debugging information, useful as a quick check when needed.

print(' Part 1 - check the first five entries for Arizona')

# Check if any of the first five entries in state_names is Arizona. If yes, print a line that

# indicates you found Arizona somewhere in the first five entries. Otherwise, print a line

# that says you didn't find Arizona in the first five entries.

# Hint: several ways to tackle this... you could use a series of if.. elif statements.

# You could use a series of if statements that keep track on any matches you find, perhaps using a boolean variable.

# You could get a slice of the first five in state_names and use a membership test.

# insert your code next - IMPORTANT... indent your code to line up with the beginning of this comment

# this indentation should happen automatically in IDLE...

# just put your cursor at the end of this line and press Enter

# end of part 1

print(' Part 2 - check the first three entries for big population Pacific or Gulf states')

# Check the first three entries in the lists, and test to see if any of them meets BOTH of the

# following conditions:

# is their population equal to or greater than 22 million, and

# do they have a coastline on the Pacific Ocean or on the Gulf of Mexico (Alaska, Hawaii, Washington, Oregon,

# California, Texas, Louisiana, Mississippi, Alabama, Florida)

# If yes, print out the name(s) of those states... you can print multiple lines as desired.

# You only need to check the first three entries... otherwise, you'd be typing a lot

# of statements.

# I am asking only for the state names in Part 2, but you can also print out their populations if you wish

# Major Hints:

# 1. Reminder about the logical operators (zyBooks Table 4.5.3 and Participation 4.5.2)

# to test multiple conditions.

# 2. Consider putting the coastal state names in a list, then doing a membership comparision

# (zyBooks Figure 4.9.1 and Instructor notes).

# insert your code next - IMPORTANT... indent your code to line up with this comment

# end of part 2

# what follows are a couple of functions that help this program.

# Later chapters of our class will cover what these functions are doing

# but for now, you can just live with confidence that each accomplishes the job described

# in the initial comment shown for each function

def get_all_states():

"""Opens a .csv file and loads lists with state names and July 2019 population data

The .csv file is assumed to have a header row, but we skip over it."""

infile = open(INPUT_FILE, 'r')

next(infile) # read and toss away the header which is the first line in the file

for line in infile:

one_line = line.split(',') # obtain one line from the file, parse it using the commas

state_names.append(one_line[0]) # append this name to the tail of the list

x = int(one_line[1]) # convert the population string into integer

state_populations.append(x) # and then append to the tail of the list, repeat the loop till EOF

infile.close()

def print_all_states():

"""Quick check that the data loaded properly"""

print(' Our lists have', len(state_names), 'state names and', len(state_populations), 'populations.')

print("state_names:", state_names)

print()

print("state_populations:", state_populations)

# call main

if __name__ == '__main__':

main()

This was the solution I was working with below. I wrote it into the program, but I keep recieving errors.
