This python library enables the decompression of *.dbc files commonly found on Brazil's DATASUS FTP server into *.dbf files.

This is a python bindings of the sibling library datasus-dbc, written in rust. Because of that, this library should be compatible with most platforms.

pip install datasus-dbc

• To decompress a *.dbc file into a *.dbf, use the decompress function:

import datasus_dbc

datasus_dbc.decompress("input.dbc", "output.dbf")

• If you have the raw bytes of a *.dbc file, you can use decompress_bytes function to obtain the decompressed *.dbf raw bytes in memory:

import datasus_dbc

with open("input.dbc", "rb") as file:
    dbf_bytes = datasus_dbc.decompress_bytes(file.read())
    print(dbf_bytes)

This library does not support reading the contents of a *.dbf file. However, you can still use one of the following libraries: simpledbf or dbfread.
