python: How to display data of a text file

Question

I am trying to read this text file and display its data. I should report product name, its value & most valuable product. I added at the end what I have tried doing so far:

Here is how the text file looks like:
item name 1 ex: hats 
quantity of item 1 ex: 12 
unit price of item 1 ex: 5.9   
item name 2 ex: jacket
quantity of item 2 ex: 13
unit price of item 2 ex: 29.9


Expected output
12 hats at 5.9 the unit. total value: 70.8
13 jackets at 29.9 the unit. total value: 390
total inventory value: 460.8
most valuable inventory: jacket: 390

what I've tried doing so far:

filename = "store.txt"

with open(filename) as f:
    content = f.read().splitlines()

content_list = [content[i * 3:(i + 1) * 3] for i in range((len(content) + 3 - 1) // 3)]

total_value = 0

for items in content_list:
    value = float(items[2])*(float(items[1]))
    print(items[1],'', items[0], '@ $', items[2], '. Value: $', value)

    total_value += value


#max_value = max(value)

print('')
print('total value: '+ str(total_value))
#print('Highest value item: ' + str(max_value))

Answer 1

getting a particular thing sliced from the text file you can use

python re package

link if want to understand more about this package

      re.split(pattern, string, flags=0)

this will return a list

       lis = [my_list[i * n:(i + 1) * n] for i in range((len(my_list) + n - 1) // n )] 

       n=size you want to break them in 
       my_list=the list you want to break

      


     file = open("store.txt")

     lis=[]
     for line in file:
     if(line.startswith("item")):
         item_name=line[line.find(":")+1:]
         lis.append(item_name.strip())
     elif(line.startswith("quantity")):
         quantity=line[line.find(":")+1:]
         lis.append(float(quantity))
     elif(line.startswith("unit")):
         unit=line[line.find(":")+1:]
         lis.append(float(unit))

    


     content_list = [lis[i * 3:(i + 1) * 3] for i in range((len(lis) + 3 - 1) // 3)]
     print(content_list)
     total_value=0
     lis2=[]
     for items in content_list:
          value = (items[2])*(items[1])
          print(items[1],'', items[0], '@ $', items[2], '. Value: $', value)
          lis2.append(value)
          total_value+=value


      max_value = max(lis2)

      print('')
      print('total value: '+ str(total_value))
      print('Highest value item: ' + str(max_value))
