Integration with Other Libraries
Polars can seamlessly integrate with other popular Python libraries, such as NumPy and pandas.
Converting to Pandas
# Convert Polars DataFrame to Pandas DataFrame
pandas_df = combined_df.to_pandas()
print(pandas_df)
Output:
Name Age Gender
0 John 25 Male
1 Alice 30 Female
2 Bob 28 Male
3 Charlie 22 Male
4 Diana 26 Female
Converting from Pandas
import pandas as pd
# Create a sample Pandas DataFrame
pandas_data = pd.DataFrame({
"Name": ["Eve", "Frank"],
"Age": [27, 35],
"Gender": ["Female", "Male"]
})
# Convert Pandas DataFrame to Polars DataFrame
polars_df_from_pandas = pl.from_pandas(pandas_data)
print(polars_df_from_pandas)
Output:
shape: (2, 3)
