serializor on Pypi

Serialization/Deserialization for Python native and NumPy/Pandas objects.

Created to be used in a project, this package is published to github for ease of management and installation across different modules.

Installation

Install from PyPi

pip install serializor

Install from github

pip install git+https://github.com/AresJef/Serializor.git

Requirements

Python 3.10 or higher.

Features

This package is designed to serialize most of Python objects into <'bytes'>, and then deserializes them back to the original (or compatiable) object.

Python natives:
- Ser <'str'> -> Des <'str'>
- Ser <'int'> -> Des <'int'>
- Ser <'float'> -> Des <'float'>
- Ser <'bool'> -> Des <'bool'>
- Ser <'datetime.datetime'> -> Des <'datetime.datetime'> [Supports Timezone]
- Ser <'datetime.date'> -> Des <'datetime.date'>
- Ser <'datetime.time'> -> Des <'datetime.time'> [Supports Timezone]
- Ser <'datetime.timedelta'> -> Des <'datetime.timedelta'>
- Ser <'time.struct_time'> -> Des <'time.struct_time'>
- Ser <'decimal.Decimal'> -> Des <'decimal.Decimal'>
- Ser <'complex'> -> Des <'comples'>
- Ser <'bytes'> -> Des <'bytes'>
- Ser <'bytearray'> -> Des <'bytearray'>
- Ser <'memoryview'> -> Des <'bytes'>
- Ser <'list'> -> Des <'list'>
- Ser <'tuple'> -> Des <'tuple'>
- Ser <'set'> -> Des <'set'>
- Ser <'frozenset'> -> Des <'frozenset'>
- Ser <'range'> -> Des <'range'>
- Ser <'deque'> -> Des <'list'>
- Ser <'dict'> -> Des <'dict'>
NumPy objects:
- Ser <'np.str_'> -> Des <'str'>
- Ser <'np.int*'> -> Des <'int'>
- Ser <'np.uint*'> -> Des <'int'>
- Ser <'np.float*'> -> Des <'float'>
- Ser <'np.bool_'> -> Des <'bool'>
- Ser <'np.datetime64'> -> Des <'np.datetime64'>
- Ser <'np.timedelta64'> -> Des <'np.timedelta64'>
- Ser <'np.complex*'> -> Des <'complex'>
- Ser <'np.bytes_'> -> Des <'bytes'>
- Ser <'np.ndarray'> -> Des <'np.ndarray'> [1-4 dimemsional]
Pandas objects:
- Ser <'pd.Timestamp'> -> Des <'pd.Timestamp'> [Supports Timezone]
- Ser <'pd.Timedelta'> -> Des <'pd.Timedelta'>
- Ser <'pd.Series'> -> Des <'pd.Series'>
- Ser <'pd.DatetimeIndex'> -> Des <'pd.DatetimeIndex'> [Supports Timezone]
- Ser <'pd.TimedeltaIndex'> -> Des <'pd.TimedeltaIndex'>
- Ser <'pd.DataFrame'> -> Des <'pd.DataFrame'>
