Final answer:
Triple quotation marks allow for multi-line strings and can contain both single and double quotes without escape characters, which single quotation marks cannot do.
Step-by-step explanation:
Triple quotation marks in programming languages, such as Python, allow for multi-line strings, which single quotation marks do not accommodate. You can put single quotation marks around a quotation within a quotation, using double quotation marks around the full quotation. However, with triple quotes, you can include both single and double quotes inside the string without needing to use escape characters. This makes it easy to include blocks of text that may have quotations or span across multiple lines without intricate formatting.
For example:
"""This is Joe's quote: 'To be or not to be' and he also mentions, "Life is what happens when you're busy making other plans."""
In this case, the triple quotation marks are used to define a string that includes both single and double quotes without any syntactical issues.
