* This is a comment blockīut in Python Multiline comment do not exist built-in like other programming languages. Usually, in other languages like C, C#, Java, etc., we can write a multi-line comment as shown below. print("Hello World") # This is a example of inline comment Multiline comments Let’s take an example to demonstrate inline comments in Python. Like single-line comments, inline comments also begin with a hash (#) sign and are followed by a space and the comment text. If you place the comment in the same line as a statement, you will have an inline comment. Let’s take an example to demonstrate single-line comments in Python.
PYTHON CODE BLOCKS CODE
The hash (#) works with only a single line of code and not on multi-line code. Single-line comments, also called block comments, start with a hash sign (#) followed by a single space and a text string.
PYTHON CODE BLOCKS HOW TO
Let us look into details on how to use these comments in Python code with examples. There are three kinds of comments we can use in Python. Python interpreter ignores the comments while executing the code and only interprets the code. Then we need to document it using the comments that explain what the code does, thus improving the readability of the code in Python.
Prevent execution of specific code blocksįor example, let’s say you have written complex business logic, formulas, algorithms, etc. Explaining the code or Metadata of the project. Comments are mainly used for the following purposes. Introduction to Python Comment BlockĬomments are used to explain the source code. Like every other programming language, Python has three different types of comments: single-line comments, multiline comments, and documentation string to comment out block of code. Comments are a piece of text in a computer program that provides more information on the source code written. ''' print( 'Text indented 2 spaces: \n ') Text = ''' \ This is the first line, Second line. try:Įxcept AttributeError: # undefined function (wasn't added until Python 3.3) def indent(text, amount, ch = ' '): Alternatively you could use the code below which will also work in earlier Python versions. This can easily be done by using the textwrap.indent() function which was added to the module in Python 3.3. You can indent the lines in a string by just padding each one with proper number of pad characters. How to indent the contents of a multi-line string in Python The first number of output is the line number and the second is the indentation. You can use Regex: import re with open( "/path/to/file") as file:įor mark, line in enumerate(file. How to extract the exact indentation of a line in a python file Use f-strings to get actual terminal width: print (f "") Resize an image and keep its aspect ratio.
