[FIXED] Create a list everytime I encounter a certain word in a str

Issue

My problem is that I wanted write a code that did that:

    input => str_of_words = '<post>30blueyellow<post>2skyearth<post>5summerwinter'
    output => post30 = ["blue","yellow"]
              post2 = ["sky","earth"]
              post5 = ["summer", "winter"]

At first I thought I could do something like

     if "<post>" in str_of_words:
         occurrence = str_of_words.count("<post>")
         #and from there I had no idea how to continue coding it

So I feel like I could ask if anyone knew some tricks to do that

Solution

You can use the nltk module:

import re
import nltk
nltk.download('words')
from nltk.corpus import words

def split(a):
    for i in range(len(a)):
        if a[:i] in words.words() and a[i:] in words.words():
            return [a[:i],a[i:]]


str_of_words = '<post>30blueyellow<post>2skyearth<post>5summerwinter'

post = {i:split(j) for i,j in dict(re.findall(r'post>(\d+)(\w+)',str_of_words)).items()}

post['30']
 ['blue', 'yellow']

post['5']
 ['summer', 'winter']

post['2']
 ['sky', 'earth']
