Hello dev community 
This is Day 2 of my Python learning journey. Today I focused on docstrings—something small but very powerful in writing clean and professional code.
What are Docstrings?
Docstrings are string literals that appear right after the definition of a function, class, or module.
They explain what the code does and act as in-code documentation.
Think of docstrings as a “manual” for your functions.
Why Use Docstrings?
Improve code readability
- Help others (and future you) understand code faster
- Work with tools like
help()and IDE hints - Make collaboration easier in bigger projects
Coding Practice
python
def greet(name):
"""Return a friendly greeting message for the given name."""
return f"Hello, {name}!"
print(greet("World"))
