Final answer:
In Python, the # symbol is used to make comments. Comments are ignored by the interpreter and are helpful for documenting code.
Step-by-step explanation:
In Python, you use the # symbol to indicate that the rest of the line is a comment. A comment is a line of text that Python will intentionally ignore. It's used to leave notes and explanations for the people reading the code, without affecting the code's functionality. Here's an example of using a comment in Python:
# This is a comment
print("Hello, world!") # This will print to the console
Neither the standalone comment nor the inline comment after the print function will interfere with how the code is run. It's important to note that comments are a vital part of writing clear and maintainable code.
