Task

📝 **Task:** Predict what the program prints.\n\nThe thread runs \`worker("A")\` to completion (\`join()\` waits), then the main thread continues. Output is deterministic because start+join serializes execution.\n\nExpected: two lines.

📋 Edit the starter code below. Tests run automatically.

💡 **Hint:** Re-read the theory if you get stuck.

🔮 Predict the output

Read the code carefully

import threading

def worker(name):
    print(name)

t = threading.Thread(target=worker, args=("A",))
t.start()
t.join()
print("done")

What will the program print? Write here:
