ZstdCompressor.
How It Works
ZstdCompressor.compress() accepts bytes in incremental chunks and may buffer some output. Call flush() to complete the frame, then concatenate the returned byte pieces in order.
Step-by-Step Example
from compression.zstd import ZstdCompressor, decompress
compressor = ZstdCompressor()
compressed_chunks = [compressor.compress(b'first ')]
compressed_chunks.append(compressor.compress(b'second'))
compressed_chunks.append(compressor.flush())
compressed_bytes = b''.join(compressed_chunks)
print(decompress(compressed_bytes))Understanding the Example
- The expression 'ZstdCompressor()' supplies the value stored as 'compressor'. This value is then used or checked by the later statements.
- The expression "[compressor.compress(b'first ')]" supplies the value stored as 'compressed_chunks'. This value is then used or checked by the later statements.
This example requires a newer interpreter or an optional standard-library component. If the import or function is unavailable, check the installed version and distribution before running it.
Where This Fits in a Real Program
A practical archive workflow has separate decisions for selection, compression, extraction and verification. When files come from other people, inspect paths, member counts and uncompressed sizes before writing anything; a successful decompression does not establish that its contents are trustworthy.
Practice: Try It Yourself
Compress two chunks separately and restore their combined content.
For this exercise, predict the result before running the changed code. Then explain the difference between the original and modified cases using the actual values, not just whether the program completed.

Common Beginner Mistakes
- Forgetting the final flush and storing a truncated compressed frame, or passing text instead of bytes.
- An empty result from compress() may be normal while buffering a frame.
