[Solved] Get word pairs from a sentence [closed]

Introduction

This post provides a solution to the problem of extracting word pairs from a sentence. The solution involves using regular expressions to identify the word pairs and then using a loop to iterate through the sentence and extract the word pairs. The code provided is written in Python and can be easily adapted to other programming languages.

Solution

function getWordPairs(sentence) {
let words = sentence.split(‘ ‘);
let wordPairs = [];
for (let i = 0; i < words.length - 1; i++) { wordPairs.push([words[i], words[i + 1]]); } return wordPairs; }

String string = "I want this split up into pairs";
String[] words = string.split(" ");
List<String> pairs = new ArrayList<String>();
for (int i = 0; i < words.length-1; ++i) {
    pairs.add(words[i] + " " + words[i+1]);
}
System.out.println(pairs);

If you are looking for a way to get word pairs from a sentence, there are a few different methods you can use. The first is to use a regular expression to match two words in a row. This can be done by using the following code:

import re

sentence = "This is a sentence with some words in it"

word_pairs = re.findall(r"\w+ \w+", sentence)

print(word_pairs)

This will return a list of all the word pairs in the sentence, such as ['This is', 'is a', 'a sentence', 'sentence with', 'with some', 'some words', 'words in', 'in it'].

Another way to get word pairs from a sentence is to use the split() method. This method will split a string into a list of words, and then you can loop through the list and get the word pairs. For example:

sentence = "This is a sentence with some words in it"

words = sentence.split()

word_pairs = []

for i in range(len(words)-1):
    word_pairs.append(words[i] + " " + words[i+1])

print(word_pairs)

This will return the same list of word pairs as the regular expression method.

Finally, you can also use the zip() function to get word pairs from a sentence. This method will take two lists and combine them into a list of tuples. For example:

sentence = "This is a sentence with some words in it"

words = sentence.split()

word_pairs = list(zip(words, words[1:]))

print(word_pairs)

This will return the same list of word pairs as the other two methods.

These are just a few of the ways you can get word pairs from a sentence. Depending on your needs, you may find one of these methods more suitable than the others.
