Python First Program
Once Python is installed and your editor (IDLE or VS Code) is set up, it's time to write your first Python program.
Python is known for its simplicity and readable syntax. Let’s create a basic script that prints something on the screen — the traditional way to begin is with a Hello, World! program.
🖥️ Writing Your First Python Program
✅ Using IDLE
-
Open IDLE.
-
Click on File > New File.
-
Type the following code:
print("Hello, World!") -
Save the file with a
.pyextension (e.g.,first_program.py). -
Press F5 to run the program.
✅ Output
Hello, World!
✅ Using VS Code
-
Open VS Code.
-
Create a new file named
first_program.py. -
Type the same code:
print("Hello, World!") -
Open the terminal inside VS Code (
Ctrl +`). -
Run the file:
python first_program.py
✅ Output
Hello, World!
🧠 How Does It Work?
The print() function is used to display output in Python.
It takes one or more arguments and writes them to the standard output (usually the screen).
Syntax:
print(object(s), sep=separator, end=end, file=file, flush=flush)
For now, just remember:
print("any message you want to show")
❗ Common Mistakes
| Mistake | Example | Fix |
|---|---|---|
| Missing quotes | print(Hello World) |
print("Hello World") |
| Wrong function name | Print("Hello") |
print("Hello") (Python is case-sensitive) |
| No parentheses (in Python 3) | print "Hello" |
print("Hello") |
💡 More Examples
print("Python is awesome!")
print("My name is John")
