π Understanding Print Statements in Python
In Python, a print statement is a function that displays output to the console or standard output. It's how your program communicates with you (or any user). Think of it as the program 'talking'.
π¬ Understanding Comments in Python
Comments, on the other hand, are notes that programmers add to the code to explain what's going on. The Python interpreter completely ignores them; they're purely for human readers. They improve code readability and maintainability.
Comparing Print Statements and Comments
| Feature |
Print Statements |
Comments |
| Purpose |
Displays output to the console |
Explains code; ignored by the interpreter |
| Execution |
Executed by the Python interpreter |
Not executed; for human readers only |
| Effect on Program |
Affects the program's output |
No effect on the program's execution |
| Syntax |
print("Hello") |
# This is a comment |
| Use Cases |
Displaying variables, debugging, user interaction |
Explaining code logic, documenting functions, leaving notes |
π Key Takeaways
- π Purpose: Print statements show output, while comments explain the code.
- βοΈ Execution: Print statements are executed; comments are ignored.
- π‘ Effect: Print statements affect output; comments don't affect execution.
- βοΈ Syntax: Print uses
print(); comments use #.
- π§ͺ Use Cases: Print for displaying data, comments for documentation.
