What character is used to delimit a string in Python?

In Python, strings are defined by enclosing text within quotes. This can be achieved using single quotes (e.g., 'Hello') or double quotes (e.g., "Hello"). Both of these options effectively serve as delimiters for string literals. By using quotes, Python recognizes the beginning and end of the string, allowing you to store and manipulate text easily.

The other options do not serve the same purpose: parentheses are typically used for grouping expressions or function calls, braces are commonly associated with defining dictionaries or sets, and brackets are used for list definitions or indexing operations. Therefore, quotes are uniquely designated for string delimiters in Python's syntax.
