pip install bincopySee the test suite: https://github.com/eerimoq/bincopy/blob/master/tests/test_bincopy.py
A basic example converting from Intel HEX to Intel HEX, SREC and binary formats:
>>> import bincopy
>>> f = bincopy.File()
>>> with open("tests/files/in.hex", "r") as fin:
... f.add_ihex(fin)
>>> print(f.as_ihex())
