What is an escape character in Python?

• A. A character used to create multi-line strings
• B. A character that allows quotes within a string
• C. A special character used in variable names
• D. A character that creates binary data

Answer: (B)

An escape character in Python is used to allow quotes to exist within a string without terminating the string itself. For example, when you want to include a quote within a string, you can use the backslash (`\`) followed by the quote character. This tells Python to treat the quote as a literal character rather than as a string-delimiting quote. For instance, to create a string that includes a quotation mark, you can write: ```python text = "He said, \"Hello!\"" ``` In this case, using the backslash before the double quote means that Python knows the quote is part of the string and not the end of it. This is crucial for managing strings that require quotes as part of their content without causing syntax errors. The other options don't accurately describe the functionality of escape characters. Multi-line strings are created using triple quotes, special characters in variable names have different rules in Python, and binary data is managed through specific data types rather than escape characters.
