Introduction
In Python, comments are lines of text that are ignored by the Python interpreter. They are ignored by the Python interpreter (or any other programming language’s compiler/interpreter) and are meant solely for human readers of the code.They are meant for human readers, allowing developers to explain or clarify parts of their code. Python Course in BangaloreComments are very helpful for making code more readable, maintaining it over time, and explaining complex logic to other developers (or even yourself).
Think of them as little signposts or annotations within your code that help explain what’s going on.
Comments in programming are non-executable lines of text that are included in the source code to provide explanations, clarifications, or additional context about the code. Python Training in Bangalore They are ignored by the compiler or interpreter when the program is executed, and are solely for the benefit of anyone reading or maintaining the code.
What are Comments?
Explanatory Notes: Comments provide context, clarify complex logic, and explain the purpose of different parts of your code.Best Python Course in Bangalore
Documentation: To describe the purpose of functions, classes, or sections of code. This is especially helpful for collaboration.
Clarification: To clarify any assumptions or decisions made in the code, helping future developers understand why certain choices were made.
Non-Executable: Top Python Training in Bangalore The interpreter skips over comment lines, so they don’t affect how your program runs.
For Humans: They are primarily intended for developers (including your future self!) who will read and maintain the code.
Debugging: To temporarily disable parts of the code during testing or debugging without deleting it.
Types of Comments in Python
Single-Line Comments:
These start with a hash symbol (#) and continue until the end of the line. Everything after the # on that line is considered a comment.A comment that occupies only one line. It starts with a # symbol, and everything following # on that line is considered a comment.Best Python Course in Bangalore
Multi-Line Comments:
While Python doesn’t have a specific syntax for multi-line comments like some other languages (e.g., /* … */ in C++ or Java), the convention for longer explanations is to use docstrings (documentation strings). Docstrings are multi-line strings enclosed in triple quotes (“””Docstring goes here””” or ”’Docstring goes here”’).You can also create comments that span multiple lines by using multiple # symbols, one at the beginning of each line.Python Training in Bangalore
Docstrings:
Docstrings are a special type of multi-line comment used specifically to describe functions, methods, classes, or modules. They are placed right after the definition and are enclosed in triple quotes.
Key Points to Remember:
Comments are ignored by the interpreter: They do not affect the execution of the program in any way.Best Python Course in Bangalore
Use comments to clarify complex code: Comments should explain “why” something is done, rather than “what” is done (the code should be self-explanatory when possible).
Keep comments concise and relevant: Over-commenting or unnecessary comments can make the code cluttered and hard to read.
