Here's the information about Python single-line comments from W3Schools:

Single-line Comments

In Python, you can use the # symbol to create a single-line comment. A single-line comment starts with the # symbol and continues until the end of the line.

Example:

x = 5 # this is a comment
print(x)

In this example, the comment is attached to the same line as the variable assignment statement. The compiler will ignore everything from the # symbol to the end of the line, which means you can use comments like this to add notes or explanations about your code.

How Single-line Comments Work

When Python reads a single-line comment, it will simply skip over the text until it reaches the end of the line. This is because Python considers everything after the # symbol as a comment and does not execute any commands following the comment.

Here's an example of what happens when you use a single-line comment:

x = 5
print(x)
this is also a comment, it will be ignored
y = 7
print(y)

In this case, the comments are attached to different lines than the code that follows. The compiler will still skip over the comments and execute the print() functions.

Best Practices

When writing single-line comments, follow these best practices:

By following these guidelines, you can make your code easier to understand and maintain.

Single-line comments

Here are more examples of how you can use single-line comments in your Python code:

x = 5  # assign x to 5
y = 3   ## this is another assignment
print(x)  # print the value of x

You can also use them for notes or explanations about specific parts of your code:

def calculate_area(width, height):
"""
This function calculates the area of a rectangle
with given width and height. The comment below
explains how this is done.
Use the formula: area = width * height
return width * height
print(calculate_area(5, 3))  # print the calculated area

In summary, Python single-line comments are used to add notes or explanations about specific parts of your code. You can use them with the # symbol, and they help make your code more readable by providing context.
