What symbol is used to indicate a comment in scripting languages like Python?

In scripting languages such as Python, the symbol used to indicate a comment is the hash sign (#). A comment is a line in the code that is not executed by the interpreter; it is meant for programmers to add notes or explanations about the code, making it easier to understand.

Using the hash sign signifies that everything following it on that line is a comment. For example:

# This is a comment

print("Hello, world!")  # This will print a greeting

This feature helps in documenting the code and providing clarity without affecting the program's functionality. Other symbols, such as the asterisk, double forward slash, or plus sign, do not serve this purpose in Python. In some other programming languages, different symbols might denote comments, but in Python, the hash sign is the standard.
