Separation of a splited string

Question

def getOnlyNames(unfilteredString):
    unfilteredString = unfilteredString[unfilteredString.index(":"):]
    NamesandNumbers = [item.strip() for item in unfilteredString.split(';')]
    OnlyNames = []

    for i in len(productsPrices):
        x = [item.strip() for item in productsPrices[i].split(',')]
        products.append(x[0])
    return products

So I'm trying to make a function that will separate a following string

 "Cars: Mazda 3,30000;     Mazda 5, 49900;"

So I will get only:

Mazda 3,Mazda 5

First I was removing the:

then I try to get only the name of the car without the price of it

Answer 1

You can use regex for this:

import re
>>> s = "Cars: Mazda 3,30000; Mazda 5, 49900;"
>>> re.findall("[:;]\W*([^:;]*?)(?:,)", s)
['Mazda 3', 'Mazda 5']
>>> s = "Mazda 3, 35000; Cars: Mazda 4,30000;     Mazda 5, 49900;"
>>> re.findall("[:;]\W*([^:;]*?)(?:,)", s)
['Mazda 4', 'Mazda 5']

Answer 2

"Cars: Mazda 3,30000;     Mazda 5, 49900;" 

• split on the colon

  • ['Cars', ' Mazda 3,30000; Mazda 5, 49900;']

• split the last item on the semicolon

  • [' Mazda 3,30000', ' Mazda 5, 49900', '']

• split the first two items on the comma.

  •  [' Mazda 3', '30000'], [' Mazda 5', ' 49900']

• take the first item of each and strip the whitespace

  • 'Mazda 3'

  •  'Mazda 5'
