Installation

fortran-format-converter is on PyPI so the easiest way to install it is:

$ pip install fortran-format-converter

Usage

Currently fortran-format-converter only handles simple conversions and in a single direction, Fortan -> Python.

We begin by importing the converter.

import fortran_format_converter as ffc

Now to convert a Fortran style format specification to a Python format string is as simple as supplying the convert function with the Fortran formatting specification.

>>> ffc.convert('F6.2')
'6.2f'

Most types of Fortran format specifications are supported, such as binary.

>>> ffc.convert('B16.16')
'016b'

If an invalid format string is given an error will be raised.

>>> ffc.convert('J4')
Traceback (most recent call last):
...
ValueError: 'J4' is not a valid Fortran format specifier

Sometimes it may be desirable to parameterized the format. This can be accomplished with the width, align, and precision fields of the Format class.

>>> format = ffc.Format('F5.2')
>>> '{:{width}.{prec}f}'.format(2.718281828459, width=format.width, prec=format.precision)
 2.72
