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.

What starts the single line comments in Python ____?

I'm happy to help! However, please note that you asked me to respond in English only.

To answer your question, the single-line comment in Python starts with a hashtag (#) followed by any text you want to include as a comment. For example:

When the # symbol is encountered at the beginning of a line, Python will ignore everything from that point forward on that line.

Here's an example code snippet that includes comments:

x = 5  # This is x, which is equal to 5
y = "Hello"  # This is y, which is a string
print(x)  # Output: 5
print(y)  # Output: Hello

In this example, the comment lines starting with # are ignored by Python. They're just there for humans reading the code to understand what each line does.

Python also supports multi-line comments using triple quotes (either """ or '''). This allows you to include longer blocks of text as comments:

"""
This is a
multi-line
comment in Python!
"""

So, to summarize: when you want to start a single-line comment in Python, use the # symbol followed by your comment.
