You may also try using these string functions.
text = " Hello World "

# Convert text to lowercase
print(text.lower()) # Output: " hello world "

# Remove leading and trailing whitespaces
print(text.strip()) # Output: "Hello World"

# Remove whitespaces and split into words
print(text.strip().split()) # Output: ['Hello', 'World']

# Join a list of words into a sentence
words = ['Learn', 'Python']
print(" ".join(words)) # Output: "Learn Python"

# Check if the stripped text starts with "Hello"
# Output: True

# Check if "Hello" contains only alphabetic characters
print("Hello".isalpha()) # Output: True

# Check if the entire original text is alphabetic (includes spaces, so False)
print(text.isalpha()) # Output: False

# Check if "123" contains only digits
print("123".isdigit()) # Output: True

# Convert text to title case (first letter of each word capitalized)
print(text.strip().title()) # Output: "Hello World"
