Question

Which method is used to concatenate strings in Python?

Hint:

For concatenating many strings, the `join()` method is faster and more efficient than using the `+` operator.

Answer 1

Step 1: Understanding String Concatenation.
String concatenation in Python refers to the process of joining two or more strings into one string. This can be done using the `+` operator or the `join()` method.
Step 2: Methods of String Concatenation.
- Using the `+` operator: This is the simplest method, where strings are concatenated directly using the `+` operator. Example: `"Hello" + " " + "World"`.
- Using the `join()` method: This method is more efficient when concatenating a large number of strings. The `join()` method is called on a separator string, and it joins all elements in an iterable. Example: `" ".join(["Hello", "World"])`.
Step 3: Conclusion.
The `+` operator and the `join()` method are the two main ways to concatenate strings in Python, with `join()` being preferred for larger lists of strings.
