What does the replace(old, new) method do to a string?
Understand the Problem
The question is asking about the behavior of the replace method in programming, specifically what it does when called on a string with given parameters. It requires understanding how string manipulation methods work.
Answer
Returns a new string with specified substrings replaced, original unchanged.
The replace(old, new) method in Python returns a new string where all occurrences of a specified substring are replaced with another substring, without modifying the original string.
Answer for screen readers
The replace(old, new) method in Python returns a new string where all occurrences of a specified substring are replaced with another substring, without modifying the original string.
More Information
The replace() method is often used for string manipulation tasks where you need to substitute parts of text, such as replacing keywords or correcting formatting. Since it returns a new string, the original string remains intact, which is an important characteristic in functional programming.
Tips
A common mistake is expecting the original string to change after calling replace(). Remember, the original remains the same; always assign the result to a new variable if you want to keep the modified string.
