How do you leave comments on python code?

In Python, you can leave comments to provide explanations or notes within your code. Comments are ignored by the Python interpreter and are not executed as part of the program. There are two ways to leave comments in Python:

1. Single-line comments: To add a comment that spans only a single line, you can use the hash symbol (#) followed by the comment text. Anything after the hash symbol on the same line is considered a comment.

Example:
```python
# This is a single-line comment
print("Hello, World!") # This is another comment
```

2. Multi-line comments: If you want to add comments that span multiple lines, you can enclose the comment text within triple quotes (''' or """). This is often referred to as a docstring, and it can be used to provide detailed explanations for functions, classes, or modules.

Example:
```python
"""
This is a multi-line comment.
It can span multiple lines.
"""
print("Hello, World!")
```

It's good practice to include comments in your code to make it more readable and understandable for yourself and others who may read or work on the code in the future.
