In a predict and run task you do not write code from scratch. You start from a small piece of working code, work out what you think it will do before you run it, and then run it to check whether you were right.

This task contains one example.

Predict

Study the code below carefully and write down a prediction of what it will do when it runs. Your prediction should use the key terms variable, assign and concatenate. You can type your prediction straight into the code as a comment, on a line starting with #.

Work out these things in particular:

• which line collects something from the user, and which line stores it
• what the variable is called, and where its contents end up in the output
• how many separate pieces are concatenated on the last line, and where every space in that sentence comes from

Only once you have written your prediction should you run the code and compare the result with what you expected.

The code

print("Hi! What's your name?")

name = input()

print("Hi " + name + "! How are you today?")

Run it, type a name and press enter. Then run it a second time with a completely different name and check that your prediction still holds. The program is the same both times; only the data it collects has changed.
