Which character is used in python to make a multi line comment? mcq
They are completely ignored by the Python interpreter. Show
Advantages of Using CommentsUsing comments in programs makes our code more understandable. It makes the program more readable which helps us remember why certain blocks of code were written. Other than that, comments can also be used to ignore some code while testing other blocks of code. This offers a simple way to prevent the execution of some lines or write a quick pseudo-code for the program. Single-Line Comments in PythonIn Python, we use the hash symbol Example 1: Writing Single-Line Comments
Output Hello world Here, the comment is:
This line is ignored by the Python interpreter. Everything that comes after
The output of this program will be the
same as in Example 1. The interpreter ignores all the text after Multi-Line Comments in PythonPython doesn't offer a separate way to write multiline comments. However, there are other ways to get around this issue. We can use Example 2: Using multiple #
Here, each line is treated as a single comment and all of them are ignored. Even though there is no unique way to write multiline comments in Python, we know that the Python interpreter ignores the string literals that are not assigned to a variable. So, we can even write a single-line comment as:
Here, we can see that the second line of the program is a string but is not assigned to any variable or function. So, the interpreter ignores the string. In a similar way, we can use multiline strings (triple quotes) to write multiline comments. The
quotation character can either be Example 3: Using String Literals to write Multi-line Comments
Here, the multiline string isn't assigned to any variable, so it is ignored by the interpreter. Even though it is not technically a multiline comment, it can be used as one. Python docstringsBy convention, the triple quotes that appear right after the function, method or class definition are docstrings (documentation strings).
Docstrings are associated with objects and can be accessed using the To learn more, visit Python docstrings.

What is multiline statement in Python?Statements in Python typically end with a new line. Python does, however, allow the use of the line continuation character (\) to denote that the line should continue. For example − total = item_one + \ item_two + \ item_three.
What is multiline comment?Multi-line comments have one or more lines of narrative within a set of comment delimiters. The /* delimiter marks the beginning of the comment, and the */ marks the end. You can have your comment span multiple lines and anything between those delimiters is considered a comment.
