Question

This string method returns a copy of the string with all leading whitespace characters removed:

A. trim()
B. strip()
C. clean()
D. erase()

Answer 1

The string method that returns a copy of the string with all leading whitespace characters removed is (Option B) strip().

Step-by-step explanation:

The strip() method is commonly used in programming, especially in languages like Python. This method removes leading and trailing whitespaces from a string. Leading whitespaces refer to any spaces or characters that appear at the beginning of the string, while trailing whitespaces are those at the end (Option B).

The strip() method, therefore, trims the string by removing both leading and trailing whitespaces. It is a versatile and efficient way to clean up strings, particularly when dealing with user input or data read from external sources where extra spaces may be inadvertently included. For example, if you have a string " hello " and you apply the strip() method, it will return "hello" with the leading and trailing spaces removed. This ensures consistency and facilitates easier processing and comparison of strings in programming.

In conclusion, the strip() method is a valuable tool for string manipulation in programming. Its ability to remove leading and trailing whitespaces makes it useful in scenarios where clean and standardized input is essential. Whether working with user inputs or processing data from files, understanding and utilizing string methods like strip() contributes to the efficiency and accuracy of code.
