What is the output of the expression len("Hello")?

• A. 4
• B. 5
• C. 6
• D. None

Answer: (B)

The expression `len("Hello")` is used to determine the number of characters in the string "Hello". The `len()` function in Python counts all characters within the provided string, including letters, spaces, and punctuation, but in this specific case, it counts only the letters. The string "Hello" consists of the following characters: 'H', 'e', 'l', 'l', and 'o', totaling to five characters. Therefore, the output of the expression is 5, confirming the correct answer. This understanding of string length is fundamental in Python programming, as it allows developers to manage and manipulate string data effectively.
