Python: Bigrams of words in a given list of strings
Python List: Exercise - 184 with Solution
Write a Python program to generate Bigrams of words from a given list of strings.
From Wikipedia:
A bigram or digram is a sequence of two adjacent elements from a string of tokens, which are typically letters, syllables, or words. A bigram is an n-gram for n=2. The frequency distribution of every bigram in a string is commonly used for simple statistical analysis of text in many applications, including in computational linguistics, cryptography, speech recognition, and so on.
Sample Solution:
Python Code:
def bigram_sequence(text_lst):
result = [a for ls in text_lst for a in zip(ls.split(" ")[:-1], ls.split(" ")[1:])]
return result
text = ["Sum all the items in a list", "Find the second smallest number in a list"]
print("Original list:")
print(text)
print("\nBigram sequence of the said list:")
print(bigram_sequence(text))
Sample Output:
Original list: ['Sum all the items in a list', 'Find the second smallest number in a list'] Bigram sequence of the said list: [('Sum', 'all'), ('all', 'the'), ('the', 'items'), ('items', 'in'), ('in', 'a'), ('a', 'list'), ('Find', 'the'), ('the', 'second'), ('second', 'smallest'), ('smallest', 'number'), ('number', 'in'), ('in', 'a'), ('a', 'list')]

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
