Question: 1 / 400

What type of comment is initiated by a hash (#) in Python?

Inline comment

In Python, a comment initiated by a hash symbol (#) is referred to as an inline comment. This type of comment is typically used to provide explanations or annotations next to a line of code, making it easier for someone reading the code to understand its purpose or the logic being implemented. Inline comments are single-line comments, meaning they start with the hash symbol and continue until the end of that line.

For instance, in the line of code like `x = 5 # This sets x to five`, the text following the hash symbol serves as a comment to explain the code. This format is highly useful for improving code readability without affecting the execution of the program.

In contrast, other comment types such as multi-line comments use triple quotes and are meant for longer descriptions or documentation that spans multiple lines, while block comments typically refer to an arrangement where multiple lines are commented out, usually using consecutive single-line comments. A "string comment" is not a recognized term in Python commenting conventions, as strings are different constructs altogether. Thus, the classification of comments based on their initiation point helps clarify their intended use and functionality in Python programming.
