Requesting help on one assignment

Question

I'm having some trouble with the problem, the instruction states to create another file that had the following text, which I did using Python IDLE which then I saved. But I do not understand what I did wrong since it states the file does not exist/work. I am requesting a video on how to solve this problem and also accepts a file name as a parameter and where to save as well.

Write a function called boy_girl that accepts a file name as a parameter. Your function should read input from that file containing a series of names followed by integers. The names alternate between boys’ names and girls’ names. Your function should compute the absolute difference between the sum of the boys’ integers and the sum of the girls’ integers. The input could end with either a boy or a girl; you may not assume that it contains an even number of names. For example, if the input file contains the following text::

Dan 3

Cordelia 7

Tanner 14

Mellany 13

Curtis 4

Amy 12

Nick 6

Then the function should produce the following console output since the boys’ sum is 27 and the girls’ sum is 32:

4 boys, 3 girls

Difference between boys' and girls' sums: 5

Answer 1

If you see a "FileNotFoundError" when you run your code; make sure that the input file in the same folder/directory as your Python file. Otherwise the problem is with your code itself.

Answer 2

file_name = 'data1.txt'

def boy_girl(file_name):

# initialize counters for the number of boy or girl names encountered

n_girl_names = 0

n_boy_names = 0

# initialize sum trackers for the integers of the names

sum_girl_names = 0

sum_boy_names = 0

with open(file_name) as F:

for i, line in enumerate(F):

data = line.strip().split(' ')

name, integer = data

# convert string integer to an integer

integer = int(integer)

# change enumeration from Python 0-based counting to 1-based counting

n =i+1

# check if even; if so, it is a girl name. If not, it is a boy name.

if n % 2 == 0:

# increment name counter by 1

n_girl_names += 1

# increment sum counter by the integer

sum_girl_names += integer

# if not even, it is a odd, a boy name.

else:

n_boy_names += 1

sum_boy_names += integer

absolute_diff = abs(sum_girl_names - sum_boy_names)

print( str(n_boy_names), 'boys', str(n_girl_names), 'girls')

print("Difference between 'boys' and 'girls' sums:", str(absolute_diff))

# run the function

file_name = boy_girl(file_name)

-I made a text file called "data1.txt" and inputted its file path at the top of the script above, "problem.py"

-When running the script, I got the desired output as specified as seen below.

>python problem1.py

4 boys 3 girls

Difference between 'boys' and 'girls' sums: 5
