We also saw how to create multi-line comments.
#INOTEBOOK COMMENT OUT CODE#
In this article, we learned why it is important to comment our code and how to use comments. As reported by the NOAD, the meaning of comment out is (computing) turn part of a program into a comment so that the computer ignores it when running the program. When you use multi-line strings in Python without assigning the string to a variable, that part of the code will be ignored. In this next example, we are going to use multi-line strings (starts and ends with three quotation marks) to nest our comment. Here's the first: # When this code runs,Ībove, we placed the # symbol on each line to continue writing our comment. Unlike most other programming languages, Python has no built-in syntax for creating multi-line comments.įortunately, there are two ways we can work around that. In this section, we'll see how to write comments that span across multiple lines. That is: print("Hello world") # Prints Hello World How to Write Multi-Line Comments in Python You don't always have to place comments above the line of code they're referencing. When we run the code, only the second line will be interpreted. When the code is being executed, the interpreter will ignore the comment and run the print() function. In the code above, I have used a comment to explain what the code does. Here's an example: #The code below prints Hello World! to the console In this section, we'll see how to add comments using Python.Ĭomments in Python start with the # symbol. The syntax for comments differs in each programming language. This is useful when other developers are reading our code, as it makes it easy to understand what each part of the code does. We can use comments to explain what each code block does.
Readability: This is very important – not just for ourselves but for other developers.
#INOTEBOOK COMMENT OUT PLUS#
Converting cells between different forms (StandardForm, InputForm) will even shuffle around newlines. 2 usb c on the left, plus 1 on the right, all three can charge the laptop. Mathematica doesn't really respect lines, it pushes working at the expression level when possible (not at the source text level). This may be because you have no use for that code at the moment, but you want to add it anyway for future functionality. There is no way to comment out a single line.
Here are some of the main reasons to comment your code: These aren't only applicable to Python, but to most programming languages. To comment on multiple lines of code in Python, use the consecutive single-line comm Show more. In this section, we'll talk about some of the general use cases for comments. This is a simple trick to comment multiple lines of a Python code at a time in Jupyter-Notebook. In this article, we'll talk about comments in Python, why they are important, and how to use them effectively in your code.
