Easy Binary File Package
Easy way to use binary files with built in class and functions.
Installation from PYPI
You can find last version of project in: https://pypi.org/project/easy-binary-file/
Command to install:
pip install easy-binary-file
Simply import and use functions or class
Example of function to dump a single value:
from easy_binary_file import dump_single_value dump_single_value("test_file_single.tmp", "test_value")
Example of function to load a single value:
from easy_binary_file import load_single_value value = load_single_value("test_file_single.tmp") print(value)
Example of instance of class to dump several values:
from easy_binary_file import EasyBinaryFile with EasyBinaryFile("test_ebf_object.tmp") as ebf: ebf.dump("First value") ebf.dump("Second value")
Example of instance of class to read all items:
from easy_binary_file import EasyBinaryFile with EasyBinaryFile("test_ebf_object.tmp", "rb") as ebf: for item in ebf: print(item)
Import functions, class or all.
from easy_binary_file import *
This is a review of class and functions content inside.
The difference between use functions vs class:
- Functions open and close file in each use (For use a lot, functions are slower than class)
- Instance of class maintain open the file until end of use (or call to

dump_ensure_space: Only dump value if space enough in disk.
dump_single_value: Open a file in the binary mode, dump a single value and close file
load_single_value: Open a file in the binary mode, load a single value, return it and close file
dump_items: Serialize one iterable in a single file
load_items: Deserialize item by item in one stream generator
quick_dump_items: Quick open a file in ab or wb mode and dump items one by one from iterator, when generator is exhausted then close the file.
quick_load_items: Quick open a file in rb mode and load items in one generator, when generator is exhausted then close the file.
EasyBinaryFile: Open (or create if not exist) a new binary file.
close: Close the binary file.
dump: Dump one single value in file.
