"""-delimited text is not actually a comment. Its a multiline string literal x = """aaa bbb""" And you can also use single quotes if you want. x = '''aaa''' The reason this might have been confused with a comment is because triple-quoted strings are often used for documentation strings, a Python feature that gives special meaning to string literals that occur as the first statement in a function or class. Those strings get associated to the function as its documentation and can even be inspected at runtime: def foo(): "my documentation string" return 17 print help(foo)
