This video installs Polars and demonstrates how to integrate with Ollama local models to do data analysis.
Code:
conda create -n polarsdf python=3.11 -y && conda activate polarsdf
conda install jupyter -y
jupyter notebook
!pip install polars pyarrow pandas ollama
import polars as pl
from datetime import datetime
df = pl.DataFrame(

datetime(2024, 7, 1),
datetime(2024, 7, 2),
datetime(2024, 7, 3),
datetime(2024, 7, 4),
datetime(2024, 7, 5),
],
"revenue": [1000.0, 1200.0, 1100.0, 1300.0, 1400.0],
"expenses": [500, 600, 550, 650, 700]
}
)
print(df)
df.write_csv("dummyfinance.csv")
df_csv = pl.read_csv("dummyfinance.csv")
print(df_csv)
df.select(pl.col("*"))
df.select(pl.col("revenue", "date"))
df.filter(
