A python library allowing conversion of large number from any base to any base.

pybaseconv

pybaseconv is a library that allows you to convert any large number (no fractions) from any base to any other base, thus freedom to choose source and/or destination bases.

There are 5 predefined bases that are supported by pybaseconv, which are:

• DEC : the decimal base "0123456789".
• BIN : the binary base "01".
• OCT : the octal base "01234567".
• HEX : the hexadecimal base "0123456789abcdef".
• FLICKER_BASE_58 & BITCOIN_BASE_58: two variations of the Base58 encoding, more info here.

Installation

pybaseconv requires Python >= 3.5 due to the usage of the type hints introduced in Python 3.5

To install pybaseconv, simply:

pip install pybaseconv

Module usage

from pybaseconv import Converter, BASE

dec2hex_converter = Converter(BASE.DEC, BASE.HEX)
print(dec2hex_converter.convert('738653'))  # returns b455d

dec2bitcoin_converter = Converter(BASE.DEC, BASE.BITCOIN_BASE_58)
print(dec2bitcoin_converter.convert('292251'))  # returns 2Vsp

dec2custom_base_converter = Converter(BASE.DEC, '*&@#$')
print(dec2custom_base_converter.convert('539'))  # returns $&@$

bin2dec_converter = Converter(BASE.BIN, BASE.DEC)
print(bin2dec_converter.convert('11112'))  # raises exception because 11112 is not a binary number

PS: when using custom bases, make sure that the digits are sorted from smallest to the largest, in order to get the appropriate conversion.
