Remember: Python reads one line at a time, top to bottom. Print shows the text inside the quotes, and an error message is a clue.
Read and answer
Read the story, then answer.
Bo learns to say helloAt Robot Club, Zara wants Bo to greet every visitor. Ms. Ito says the language is called Python, and a computer reads it one line at a time. Zara types print("Hello") and runs it, and Bo's screen shows the word Hello. She adds a second line, and Python reads line one and then line two, from the top down. Leo tries his own line, but he forgets the last quote. A message pops up and points at his line. Zara says it is an error message, and it is a clue, not a telling-off.

3True Print tells the computer to show a message.
4Hello, then I am Bo Python reads line 1 first and line 2 next, so Hello comes before I am Bo.
