What does the '#' symbol do in Python?

I'd be happy to help you with that!

The # symbol is used for commenting out code in Python. When a line of code starts with the #, everything after it on that line is ignored by the interpreter. This means that if you have some code and you want to add a note or a reminder about what that code does, you can use the # symbol to comment it out.

Here's an example:

x = 5  # this variable holds the value of 5
y = x + 3
print(y)  # prints 8

In this case, the comments (#) are used to explain what each line of code does. They don't affect the execution of the program in any way.

Commenting out code is a good practice because it helps other developers (or yourself, if you come back to this code later) understand what the code is supposed to do. It's also useful for temporarily disabling parts of your code while you're testing or debugging something else.

You can use the # symbol anywhere in a line of code, not just at the beginning. For example:

x = 5; y = x + 3  # this is equivalent to the previous example
print(y)  # prints 8

In this case, everything after the # symbol on that line is ignored.

One important thing to keep in mind is that Python doesn't have multi-line comments. This means you can only comment out one line of code at a time using the # symbol. If you want to comment out multiple lines, you'll need to use separate # symbols for each line, or use a different commenting system (like docstrings or triple quotes).

Overall, the # symbol is an important part of Python's syntax and is used extensively in coding to make your code more readable and easier to understand.

Would you like me to elaborate on anything else about Python's commenting system?
