Certified Entry-Level Python Programmer (PCEP-30-02) — Question 48

Which of the following statements can be used to return the length of the given string str?

Answer options

• A. str.size()
• B. str._len_()
• C. size(str)
• D. len(str)

Correct answer: D

Explanation

The function len(str) is the correct way to determine the length of a string in Python. The option str.size() does not exist in Python for strings, while str._len_() is not a valid method, and size(str) is not a built-in function for obtaining string lengths.
