# Getting 27 for the “white” count instead of 28

If you think of your program like a big math expression to be simplified with parts of it cancelling out and removed … then yeah there’s a fair bit you can get rid of in that.

For example, a lot of your loops are iterating through the same thing. An entry from the input. They could all be the same loop.

Splitting on “&” can be done regardless of whether there’s a “&” in it. You have two separate cases for that, they’re the same thing.

This really helped thanks.

I am stuck at #11 where it’s asking for customer, sales, and thread_sold.
Does anyone here have the solution to this, or the entire project?

I have managed to produced transactions_clean to be a list of lists of strings.
e.g.

``````print(transactions_clean[0])
['Edith Mcbride   ;\$1.21   ;   white ; 09/15/17']
print(transactions_clean[99])
['Myrtle Morris \n;   \$22.66   ; green&white&blue;09/15/17']
``````

Is this what we are suppose to have right up to this point?

If not, then what is transactions_clean suppose to look like?

This is what I get…

``````['Edith Mcbride', '\$1.21', 'white', '09/15/17']
# ...
['Myrtle Morris', '\$22.66', 'green&white&blue', '09/15/17']
``````

It is still possible for you to finish cleaning up the content you have to this point.

``````transactions_cleaner = []
for x in transactions_clean:
transactions_cleaner.append(x.split(';').strip())

print (transactions_cleaner[0])
``````

See what that looks like. In review, how could we write the earlier code so this step is not needed (that is, so we get the result shown above).

Thank you mtf
I was able to clean up the code.

always i got 0 please anyone can help me solve this issue thanks, i’m begin confused !

what’s wrong with this code please, I’m begin confused for hours!

Perhaps when you joined the forum you skipped over the part about how to make your code look like code when it is posted? Guess now is a good time to find out that we don’t hold hands, here. Get with the program or expect hand outs which may not be as fitting as one would hope for.

can someone explain please why this works? what does [::] mean ?
Struggled with this problem for two days and I cant seem to get my head around it

Using list[::1] is a way of slicing a list in python that may not have been introduced in the lessons so far. Unless it has been covered in lessons it is probably wise to attempt to complete the problem without it so as to practice the skills you’ve covered to that point.

As for the slicing, if you’re curious it works as [start:end:step]. Defaults for these are effectively [0:-1:1] so when including the colons without a value you are using the default.

So for a list of 1:20 (inclusive) where we wanted every thrid value (starting at index 0)-

``````the_list = list(range(1, 21))
every_third_value = the_list[::3]
print(every_third_value)
output: [1, 4, 7, 10, 13, 16, 19]
``````

For the same list if we wanted every thrid value starting at the 7th index but finishing before the 17th index-

``````the_list = list(range(1, 21))
every_third_value = the_list[7:16:3]
print(every_third_value)
output: [8, 11, 14]
``````

Thank you!!! I’ve been in the same problem tooooooooo.

``````customers = []
sales = []

for transaction in transactions_clean:
customers.append(transaction[0])
sales.append(transaction[1])

total_sales = 0

for sale in sales:
total_sales += float(sale.strip("\$"))

print(sales)
``````

I am typing this code into the program which more or less the same as all of the other lines on here but when I print ‘total_sales’ I get a weird number (1498.7400000000005)

Anyone know why?
Thanks

That is because computers work with binary (floating point arithmetic). You can always round to 2 decimal places.

Thank you guys!!! I really appreciate it.

Hello @promethus17! Could you explain what problems you are having?

Hey there, for some reason I get an EOF error when I attempt to make the strings floats in the last few lines. I assume the reason for this error is the fact for some reason the name ‘Hudson’ is randomly between all the numbers in my sales list.

Does anyone have a clue where I messed up?

``````daily_sales_replaced = daily_sales.replace(';,;', 'x')
daily_transactions = daily_sales_replaced.split(',')
#print(daily_transactions)
daily_transactions_split = []
for transaction in daily_transactions:
daily_transactions_split.append(transaction.split('x'))
#print(daily_transactions_split)
transactions_clean = []
for transaction in daily_transactions_split:
transaction_clean = []
for data_point in transaction:
transaction_clean.append(data_point.replace("\n", "").strip(" "))
transactions_clean.append(transaction_clean)
#print(transactions_clean)

customers =[]
sales =[]
for transactions in transactions_clean:
customers.append(transactions[0])
sales.append(transactions[1])

print(sales)

total_sales = 0
for sale in sales:
total_sales1 += float(sale.strip('\$'))
``````

When I copy and run your code, I see this error:

NameError: name ‘total_sales1’ is not defined

pointing to this line:

No EOF error was thrown. Is there additional code, that you didn’t include?
