how to download files into local from remote

[lizzzcai]

Hi, thanks for the project. I am exploring the python sdk, want to check any example on how to efficiently download files from s3 to local like boto3.

currently I am trying is:

# Read the file from the S3 bucket
file_content = op.read("test.txt")

# Print the file content to verify
print(file_content)

# write file to local
with open("test.txt", "wb") as f:
    f.write(file_content)

Hi, please try read like a file:

import opendal
import polars as pl

# Init an operator.
op = opendal.Operator("fs", root="/tmp")

# Create a DataFrame.
df = pl.DataFrame({"name": ["Alice", "Bob"], "age": [20, 30]})
print(f"df: {df}")

# Open and write the DataFrame to the file.
with op.open("test.csv", mode="wb") as file:
    df.write_csv(file)

# Open and read the DataFrame from the file.
with op.open("test.csv", mode="rb") as file:
    read_df = pl.read_csv(file)
    print(f"read_df: {read_df}")
