MessagePack is an efficient binary serialization format that allows data exchange among multiple languages. It is similar to JSON but faster and more compact. The msgpack library in Python provides the necessary tools to work with this format, offering both CPython bindings and a pure Python implementation.
Before you can start reading and writing MessagePack data, you need to install the msgpack library, which can be done using pip:
pip install msgpack
pip install msgpack
Here is a simple example of how to use MessagePack to serialize and deserialize data:
import msgpack
# Serialize key-value pairs or file-like object
data = {'key': 'value', 'number': 42}
packed_data = msgpack.packb(data, use_bin_type=True)
# Deserialize data
unpacked_data = msgpack.unpackb(packed_data, raw=False)
print(unpacked_data)
import msgpack
# Serialize key-value pairs or file-like object
data = {'key': 'value', 'number': 42}
packed_data = msgpack.packb(data, use_bin_type=True)
# Deserialize data
unpacked_data = msgpack.unpackb(packed_data, raw=False)
print(unpacked_data)
import msgpack
from io import BytesIO
# Create a buffer for streaming data
buf = BytesIO()
for i in range(100):
buf.write(msgpack.packb(i))
buf.seek(0)
# Unpack data from the buffer
unpacker = msgpack.Unpacker(buf)
for unpacked in unpacker:
print(unpacked)
import msgpack
from io import BytesIO
# Create a buffer for streaming data
buf = BytesIO()
for i in range(100):
buf.write(msgpack.packb(i))
buf.seek(0)
# Unpack data from the buffer
unpacker = msgpack.Unpacker(buf)
for unpacked in unpacker:
print(unpacked)
