Running a Python Program

What Does Running a Python Program Mean?

Running a Python program means executing the instructions written in Python code so the computer performs a task and shows the output.

After writing code, we run the program to:

• Check whether it works correctly
• See the output
• Find errors and fix them

Real-Life Analogy

Running a Python program is like pressing the Play button on a game after setup.

It is also like doing homework and showing it to a teacher to check the result.

The computer reads each instruction step by step and follows it.

Example:

print("Hello")

When you run this program, Python displays:

Hello

Ways to Run a Python Program

You can run Python programs using:

• Python IDLE
• Visual Studio Code (VS Code)
• Command Prompt (Windows)
• Terminal (Mac/Linux)

Python Run Command Syntax

python filename.py

Example:

python hello.py

This runs the Python file named hello.py.

Steps to Run a Python Program in IDLE

1. Open Python IDLE
2. Click File → New File
3. Write your code
4. Save it as filename.py
5. Click Run → Run Module
6. View the output in Python Shell

Example:

print("Welcome to Python")

Running Python Using Command Prompt

1. Open Command Prompt
2. Go to the file location
3. Type:
   

   python filename.py

4. Press Enter

Example:

print("My first program!")

Output:

My first program!

Why Running a Program is Important

Running Python programs helps you:

• Test your code
• See output
• Find errors
• Improve programs
• Learn coding faster

➤ Summary

• Running means executing a program
• It displays the output of code
• Python programs run in IDLE, VS Code, Command Prompt, or Terminal
• Files should be saved with .py extension
• Running helps find errors and check results

➤ Tips

• Always save the file before running
• Start with simple print() programs
• Check spelling, brackets, and quotes
• Practice running programs often
