Core ideas

• Programs are step-by-step instructions for the computer.
• Python uses indentation (4 spaces) for blocks — not curly braces.
• print() displays output; # starts a comment.

First program

print("Hello, future programmer!")
print("You just ran your first instruction!")

Setup checklist

• Install Python 3 from python.org
• Install VS Code + Python extension
• Run files: python my_script.py
• Read error messages — they point to the line number

Common mistakes

• Expecting the computer to “understand” vague instructions
• Skipping practice and only watching videos
• Ignoring error messages instead of reading them
