How do you comment a single line in Python?

In Python, the correct way to comment a single line is by using the # symbol. When you place a # before your comment text, Python interpreter ignores everything on that line that comes after the #. This is a fundamental feature in many programming languages, allowing developers to add remarks or explanations within the code for better readability or to temporarily disable code without deleting it.

For example:

# This is a comment

print("Hello, World!")  # This will print "Hello, World!" to the console

The other options are used in different programming languages but not in Python. The // symbol is typically used for single-line comments in languages like C++, Java, and JavaScript. The /* */ symbols are used for multi-line comments in languages such as C and Java as well. The -- symbol is found in SQL for comments within queries, but it is not valid for use in Python.
