Count Number of Words in a String Program Code

# Python program to count words in a string
text = "  Hello   world!  Python programming.  "

# Method 1: Using split() (simplest)
words1 = text.split()
count1 = len(words1)

# Method 2: Manual counting
count2 = 0
in_word = False
for char in text:
    if char.isspace():
        in_word = False
    elif in_word == False:
        in_word = True
        count2 = count2 + 1

# Method 3: Using regular expressions
import re
words3 = re.findall(r'\b\w+\b', text)
count3 = len(words3)

print("Original text:", repr(text))
print("Word count (split):", count1)
print("Word count (manual):", count2)
print("Word count (regex):", count3)
print("Words found:", words1)
