Question

Python Programming Problem:

If I have to separate lists, one contains a large string of paragraphs of words, and one contains just words, how can i iterate the words in my second list and compare it to my paragraph list to see how many times that word has occurred?

List1 = ['paragraph.......']

List2 = ['words', 'words', 'words'......]

these are just minimal examples

how do i approach this problem?

apprently numpy helps with processing time for something like this? cuz the lists could get quite big

Answer 1

You need to use numpy's char.count () function, it returns the number of times a word is present in a paragraph

Below is a naive example just to demonstrate how to use it.

==================================================================================

import numpy as np

paragraphs = np.array(
    ['the fox jumped and the fox drowned and the fox survived', 'the brown fox and the black fox fought in the mud.'])
words = np.array(['and', 'fox', 'the'])

for word in words:
    for paragraph in paragraphs:
        count = np.char.count(paragraph, word)
        print(paragraph, 'contains', count, '\"', word, "\"", 'word(s).')
