FIX THE ERROR, MY CODE IS THERE FOR REFERENCE. Thank you!

Contents of units.txt

$10$

$123$

$95$

$285$

$64$

Write some code that creates a file named totals.txt in which each line is the sum of all the item counts per container section. Continuing the above example, the following is the example result:

Contents of totals.txt

$228$

$349$

def calculate$\_$totals$($input$\_$file, output$\_$file$)$:

totals $=[]$ # List to store total counts for each container section

current$\_$total $=0$ # Variable to hold the sum for the current section

Step $1$: Read the file line by line

with open$($input$\_$file, $\text{'}$r$\text{'})$ as file:

for line in file:

line $=$ line.strip$()$ # Remove any leading or trailing whitespace

if line $=="-"$: # If a dash is encountered, save the current total

totals.append$($current$\_$total$)$ # Append the sum $($even if it's zero$)$

current$\_$total $=0$ # Reset the total for the next container section

else:

current$\_$total $+=$ int$($line$)$ # Add the item count to the current total

Step $2$: After finishing, append the last section$\text{'}$s total only if it wasn't followed by a dash

if current$\_$total $>0$: # If there's an unhandled section at the end, add it

$|$ totals.append$($current$\_$total$)$

Step $3$: Write the totals to the output file

with open$($output$\_$file, $\text{'}$w$\text{'})$ as outfile:

for total in totals:

$|$ outfile.write$($f$"$tal$\}$

$")$ # Write each total on a new line

calculate$\_$totals$(\text{'}$units$.$txt$\text{'},$ 'totals.txt$\text{'})$
