Multiline comments in Python

Python comments are annotations or notes that are used to explain the purpose or functionality of a piece of code.

In Python, there are two ways to write multi-line comments:

  1. Starting each line with the # character, which indicates that the entire line is a comment.
  2. Enclosing the comment in a set of triple quotes """ """ or ''' '''.

Consecutive single-line comment

You can create multi-line comments by starting each line with the # character. This is a simple and easy way to add comments to your code, and is useful when you want to quickly add a comment to multiple lines of code.

Following is an example of using the # character to create a multi-line comment:

# This is a multi-line comment. # It can be used to document your code, # provide explanations, or write notes. print("Multi-line Comments")
# Output: Multi-line Comments

In the above example, each line starts with the # character, which tells Python to treat the entire line as a comment. This is useful for adding comments to multiple lines of code, without having to enclose the entire block in triple quotes.

Using a Multi-line string as a comment

Follwoing is an example of using triple quotes to write a multi-line comment:

""" This is a multi-line comment. It can be used to document your code, provide explanations, or write notes. """ print("Multi-line Comments")
# Output: Multi-line Comments

In the above code, the triple quotes """ """ or ''' ''' enclose a multi-line comment. Anything inside the triple quotes will be treated as a comment, even if it spans multiple lines.

Docstrings (Documentation Strings)

Triple quotes are also commonly used to write documentation strings (docstrings) for functions, classes, and modules. Following is an example:

def add_numbers(a, b): """ This function takes two numbers as input and returns their sum. Parameters: a (int or float): The first number to be added. b (int or float): The second number to be added. Returns: The sum of a and b. """ return a + b

In the above example, the triple quotes enclose a docstring that describes what the add_numbers() function does, what arguments it takes, and what it returns. Docstrings are used to document the purpose and usage of a function or module, and can be accessed using the __doc__ attribute.

Multi-line comments and docstrings are important tools for writing clear and maintainable code. They provide explanations and context that can help other programmers understand your code and make it easier to maintain over time.

Single line comment in Python

In Python, single-line comments are denoted by the hash character (#). Any text that follows the hash character on a line is ignored by the Python interpreter.

# This is a single-line comment in Python print("Hello, World!") # This is another single-line comment
#Output: Hello, World!

In the above example, the first line is a single-line comment that does not affect the output of the program. The second line is a Python statement that prints the text "Hello, World!" to the console, and the comment that follows the statement is also ignored by the interpreter.

How to multi line comments in python

In Python, single-line comments are denoted by the hash symbol (#), while multi-line comments can be enclosed in triple quotes (''' ''') or within parentheses with the hash symbol (#) at the beginning of each line. Comments in Python are ignored by the interpreter and do not affect the execution of the program.
