How to convert a for loop output into a python list

I'm new to Python, sorry for the level of this question.

This is my output (prices from a website). I'm wondering how to convert them into a list of ints

for price_list_items in price_list:
        for values in price_list_items:
            x= values.rstrip(' zł')
            print(x)

479 000
355 000
269 000
499 000
289 000

The desired result will like this [479 000,355 000,... ]. Also, I want to be able to perform basic with the values. I found this thread How to convert a for loop output into a list (python), but it didn't help me.

lista = []

for price_list_items in price_list:
        for values in price_list_items:
            x= values.rstrip(' zł')
            lsita.append(x)

lista = ['479 000', '350 000']
for idx, item in enumerate(lista):
        item = item.split()
        item = ''.join(item)
        lista[idx] = int(item)

print(lista)

~/python/stack$ python3.7 sum.py [479000, 350000]

Change your last line to append to lista instead of print. Now we have lista = ['479 000', ...] but we want ints to perform operations on.

So we can then enumerate our list, from there we can split() and join() to get to here lista = ['479000', ...] then we can just use int(item) and put them back into lista as ints

For fun we could do some map and just go from:

lista = ['479 000', '350 000']
lista = list(map(lambda x: int(''.join((x.split()))), lista))

It looks like your string is meant to be a series of 6-digit numbers but both the individual number-parts, for lack of a better term, are split by spaces and the numbers themselves are split by newlines. The solution, therefore, is to remove the space in between number-parts, converting the result to an integer, like this:

int(part.replace(' ', '')) # Finds all instances of space and replaces them with nothing

Putting this in a list-comprehension, we have:

numbers = [int(l.replace(' ', '')) for l in str]

UPDATE

Since you've posted your code, I can give you a better answer.

[ int(v.rstrip(' zł').replace(' ', '')) for price_list_items in price_list for v in price_list_items ]
