Final answer:
In Python, the '#' symbol is used to denote the start of a comment, which helps in code readability and debugging.
Step-by-step explanation:
The symbol that marks the beginning of a comment in Python programming is #. Unlike other programming languages like C++ or Java that use // for single line comments, Python uses the hash symbol. Comments are crucial for making code more readable and can be used to explain complex sections of code or to temporarily disable certain lines of code during debugging.
In Python, the symbol '#' is used to indicate the beginning of a comment. Comments are non-executable lines intended for human readers to understand the code. When the Python interpreter encounters a '#' symbol, it ignores the rest of the line.
feature is crucial for code documentation, explaining functionality, or temporarily disabling code during testing. Well-commented code enhances readability and collaboration in programming projects, allowing developers to convey insights, context, or explanations within the source code without affecting the program's execution.
Effective use of comments is a best practice for maintaining clear and comprehensible code in Python and many other programming languages
