Tip: paste this code into an empty cell, and the marimo editor will create cells for you
import marimo
__generated_with = "0.15.5"
app = marimo.App()
@app.cell
def _():
    import marimo as mo
    return
@app.function
async def wait_for(seconds):
    import asyncio
    print(f"Waiting for {seconds} seconds ...")
    await asyncio.sleep(seconds)
    print("Done!")
@app.cell
async def _():
    await wait_for(1)
    return
if __name__ == "__main__":
    app.run()
