Your first Python instruction
Change a message, then run it.
Let's type real instructions.
In programming, a single instruction is often called a statement. Here is one:
PythonA single statement.
print("Hello, DNA!")→ Hello, DNA!
When you press Run code, Python reads the statement from top to bottom and carries it out. This one tells Python to display the message on a screen.
Predict first
What do you expect to see in the output?
print("Hello, DNA!")A common mistake
The quotes must surround the text and stay directly around it. If you remove one quote, Python gets confused. The editor will show you a red error — that's a good thing! Errors are how we learn.
Your task
Change the message
- Change the message inside the quotes to: Hello, DNA!
- Keep the exact punctuation and capitalization.
Remember
print("message") is a statement. It makes Python display text. You change what it shows by changing what's inside the quotes.
