convert size package

Overview

The File Size Converter module provides functions for converting file sizes between different units in both IEC (binary) and SI (decimal) formats. It includes functionality for getting the full name of a unit from its abbreviation and converting sizes between units.

Features

• Convert sizes between different IEC units (e.g., Bytes to Kibibytes).
• Convert sizes between different SI units (e.g., Bytes to Kilobytes).
• Retrieve the full name of a unit from its abbreviation.
• Support for both IEC (binary) and SI (decimal) unit systems.

Installation

pip install wolfsoftware.convert-size

Usage

Importing the Module

import wolfsoftware.convert_size as fsc

Converting Sizes

To convert a size between different units, use the convert_size function. You can specify whether to use SI units by setting the si_units parameter.

# IEC conversion example
size_in_gib = fsc.convert_size(1024, 'MiB', 'GiB')
print(size_in_gib)  # Output: 1.0

# SI conversion example
size_in_gb = fsc.convert_size(1000, 'MB', 'GB', si_units=True)
print(size_in_gb)  # Output: 1.0

Getting the Full Name of a Unit

To get the full name of a unit from its abbreviation, use the get_name_from_code function.

# IEC unit name example
unit_name = fsc.get_name_from_code('KiB')
print(unit_name)  # Output: Kibibyte

# SI unit name example
unit_name = fsc.get_name_from_code('KB', si_units=True)
print(unit_name)  # Output: Kilobyte

Functions

convert_size(size: float, start_unit: str, end_unit: str, si_units: bool = False) -> float

Convert a size between units, either IEC or SI.

• size (float): The original size.
• start_unit (str): The starting unit abbreviation.
• end_unit (str): The ending unit abbreviation.
• si_units (bool): If True, use SI units; otherwise, use IEC units.
• Returns (float): The converted size.
• Raises ValueError: If the unit abbreviations are not valid.

get_name_from_code(unit: str, si_units: bool = False) -> str

Get the full name of a unit from its abbreviation.

• unit (str): The unit abbreviation.
• si_units (bool): If True, use SI units; otherwise, use IEC units.
• Returns (str): The full name of the unit.
• Raises ValueError: If the unit abbreviation is not valid.

get_name_from_code_iec(unit: str) -> str

Get the full name of an IEC unit from its abbreviation.

• unit (str): The IEC unit abbreviation.
• Returns (str): The full name of the IEC unit.
• Raises ValueError: If the unit abbreviation is not valid.

get_name_from_code_si(unit: str) -> str

Get the full name of an SI unit from its abbreviation.

• unit (str): The SI unit abbreviation.
• Returns (str): The full name of the SI unit.
• Raises ValueError: If the unit abbreviation is not valid.

Error Handling

The module raises ValueError exceptions for invalid unit abbreviations. Ensure that you handle these exceptions in your code:

try:
    size_in_gib = fsc.convert_size(1024, 'MiB', 'GiB')
except ValueError as e:
    print(e)
