Working with text

Clean up text, change its case, and count characters.

Clean and change text

A method is called after a dot. strip() removes whitespace from both ends. lower() returns lowercase text. These methods return new strings; assign the result to keep it.

label = "  HELLO  "
clean = label.strip()
print(clean.lower())

Output

hello

Count characters

len() returns the number of characters in this example. Spaces count too. upper() returns uppercase text.

word = "hello"
print(len(word))
print(word.upper())

Output

5
HELLO

Working with text

Compare the original text with the cleaned result.
Count the characters before running the example.
