import bz3

with open("test_inp.txt", "rb") as inp, open("compressed.bz3", "wb") as out:
    compress_file(inp, out, 1000 * 1000)

with open("compressed.bz3", "rb") as inp:
    test_file(inp, True)    

with open("compressed.bz3", "rb") as inp, open("output.txt", "wb") as out:
    decompress_file(inp, out)

print(decompress(compress(b"12121")))

with bz3.open("test.bz3", "wt", encoding="utf-8") as f:
    f.write("test data")

with bz3.open("test.bz3", "rt", encoding="utf-8") as f:
    print(f.read())
