This is particularly useful when it comes to comments. When commenting on Python code, the comments are highlighted so that you can clearly see that the code isn’t running. And when you have multi-line comments
18.2. Multiline comment It’s a text that’s surrounded by a delimiter ( ””“) at the beginning and conclusion of the comment. There should be no whitespace between the delimiter and the next delimiter ( ””” ). When a comment spans more than one line, these comments are used. "...
Inline comments can appear after any line of Python code. They can even appear in the middle of a multiline Python expression.For example, here's a function that contains a fairly complex Python expression:def is_leap_year(year): return year % 4 == 0 and (year % 100 != 0 or year...
If you press Enter inside the expression, you’ll create a new empty line instead:The ability to recall and edit multiline statements is a huge time-saver and will make you more efficient when working with the REPL.Another convenience coming in Python 3.13 is proper support for pasting code...
Multiline expressions Inline comments The same type of quote as the containing f-string The PEP proposed a syntactic formalization of f-strings along with a new implementation that takes advantage of the PEG parser that joined the language in Python 3.9. With Python 3.12, the f-string grammar ...
Python does not have multiple-line commenting feature. You have to comment each line individually as follows − # This is a comment.# This is a comment, too.# This is a comment, too.# I said that already. Using Blank Lines A line containing only whitespace, possibly with a comment, ...

1 Whatever you call it,2 its effect lasts only to the end of the line on which it appears. Python does not have a multiline comment. You need to explicitly begin each comment line or section with a #. >>> # I can say anything here, even if Python doesn't like it, ... # ...
