📘 R25 Regulation 🎓 I Year 📚 II Semester 🐍 Python Programming 🧪 Lab Program
Selected Program

single letter words

← All Python Programs

Aim:

☛   The wordlist I provided, words.txt, doesn't contain single letter words. So you might want to add "I", "a", and the empty string.

Solution :


Text File:words.txt 

apple
banana
cat
dog
elephant

PROGRAM: (single_letter.py) 

 
def load_words(filename):
	with open(filename, "r") as file:
		words = [line.strip() for line in file]

	# Add missing single-letter words and empty string
	if "" not in words:
		words.append("")
	if "I" not in words:
		words.append("I")
	if "a" not in words:
		words.append("a")
	
	return words
# Sample usage
words = load_words("words.txt")
print("Total number of words:", len(words))
print("Sample words:", words[:10])

OUTPUT: 

 
Total number of words: 8
Sample words: ['apple', 'banana', 'cat', 'dog', 'elephant', '', 'I', 'a']
