from codetiming import Timer
from datetime import date
import polars as pl

# Quickly spin-up a 1,000,000 element DataFrame.
df = pl.DataFrame(
    {
        "Int": range(250_000),
        "Float": 123.456789,
        "Date": date.today(),
        "String": "Test"
    }

# Export to Excel from polars.
with Timer():
    df.write_excel("dataframe_pl.xlsx")
