Keeping this in view, which symbol is used in Python to create a comment?Single-line comments are created simply by beginning a line with the hash (#) character, and they are automatically terminated by the end of line. Comments that span multiple lines – used to explain things in more detail – are created by adding a delimiter (“””) on each end of the comment.
Many of the examples in this manual, even those entered at the interactive prompt, include comments. Comments in Python start with the hash character, # , and extend to the end of the physical line. A comment may appear at the start of a line or following whitespace or code, but not within a string literal.
what is comment which operator is used to write comment in Python give example?
Comments in Python start with a # character. However, alternatively at times, commenting is done using docstrings(strings enclosed within triple quotes), which are described further in this article.
How do you comment out on a keyboard in python?

How to comment Code: Primarily, a single “block” comment should be placed at the top of the function (or file) and describe the purpose the code and any algorithms used to accomplish the goal. In-line comments should be used sparingly, only where the code is not “self-documenting”. Check the answer of

It can also be used to mean “between”, or in other word, to slice an object such as a list. >>> a = [1, 2, 3, 4] >>> a[:] # All indexes, same as a. [1, 2, 3, 4] >>> a[0:4] # First(Zeroth in python) index to the fourth (last one here)
Comment Syntax Comments in Python begin with a hash mark ( # ) and whitespace character and continue to the end of the line. Because comments do not execute, when you run a program you will not see any indication of the comment there. Comments are in the source code for humans to read, not for computers to execute. Read:
Unlike other programming languages Python doesn’t support multi-line comment blocks out of the box. The recommended way to comment out multiple lines of code in Python is to use consecutive # single-line comments. This is the only way to get “true” source code comments that are removed by the Python parser.
Python Comments. Comments can be used to explain Python code. Comments can be used to make the code more readable. Comments can be used to prevent execution when testing code.
To write a comment in Python, simply put the hash mark # before your desired comment: # This is a comment. print(“This will run.”) # This won’t run. # So you can’t just do this in python. /* You can easily write multiline comments in Java */

A comment is any text in a program’s code, script, or another file that is not meant to be seen by the user running the program. Comments help make code easier to understand by explaining what is happening and can help prevent portions of a program from executing. In the image is an example of an HTML comment.
There is no such feature as a multi-line comment. # is the only way to comment a single line of code. Many of you answered ”’ a comment ”’ this as their solution. It seems to work, but internally ”’ in Python takes the lines enclosed as a regular strings which the interpreter does not ignores like comment using # .
