Count frequency of words in a sentence Program Code

# Count frequency of words in a sentence
sentence = "the quick brown fox jumps over the lazy dog the quick brown fox"
print("Sentence:", sentence)

# Split into words and count
words = sentence.split()
word_freq = {}
for word in words:
    word_freq[word] = word_freq.get(word, 0) + 1

print("\nWord frequencies:", word_freq)

# Display sorted by word
print("\nSorted by word:")
for word in sorted(word_freq.keys()):
    print(f"  {word}: {word_freq[word]}")

# Display sorted by frequency (most common first)
print("\nSorted by frequency (most common):")
for word, count in sorted(word_freq.items(), key=lambda x: x[1], reverse=True):
    print(f"  {word}: {count}")

# Find most common word
most_common = max(word_freq, key=word_freq.get)
print(f"\nMost common word: '{most_common}' appears {word_freq[most_common]} times")
