When working with Python scripts, it is often helpful to add comments to your code to provide explanations or reminders for yourself or other developers. In this article, we will explore three different ways to add comments to a Python script.
Option 1: Using the ‘#’ symbol
The most common way to add comments in Python is by using the ‘#’ symbol. Any text that follows the ‘#’ symbol on the same line is considered a comment and is ignored by the Python interpreter. Here is an example:
# This is a comment print("Hello, World!")
In the above code, the comment “This is a comment” is ignored by the interpreter, and only the “Hello, World!” message is printed to the console.
Option 2: Using multi-line strings
If you have a longer comment that spans multiple lines, you can use triple quotes to create a multi-line string. Although this is not the intended use of multi-line strings, it can be a convenient way to add comments. Here is an example:
""" This is a multi-line comment that spans multiple lines. """ print("Hello, World!")
In this case, the multi-line comment is also ignored by the interpreter, and only the “Hello, World!” message is printed.
Option 3: Using docstrings
Docstrings are used to provide documentation for functions, classes, and modules in Python. However, they can also be used as comments within a script. Docstrings are enclosed in triple quotes and are typically placed at the beginning of a function, class, or module. Here is an example:
def say_hello(): """ This is a docstring comment for the say_hello function. """ print("Hello, World!") say_hello()
In this case, the docstring comment is ignored by the interpreter, and the “Hello, World!” message is printed when the function is called.
After exploring these three options, it is clear that using the ‘#’ symbol is the most straightforward and commonly used method for adding comments in Python scripts. It is concise, easy to read, and widely recognized by Python developers. Therefore, option 1 is the recommended approach for adding comments to your Python code.
