Add support to Python 2.7.x

[lmar76]

Hi Daniel,

I have successfully used julian package with Python>=3.5. Now I would need to use it with Python 2.7 but unfortunately it is not possible to import it:

>>> import julian
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/mmfi/.local/lib/python2.7/site-packages/julian/__init__.py", line 1, in <module>
    from julian.julian import to_jd, from_jd
  File "/home/mmfi/.local/lib/python2.7/site-packages/julian/julian.py", line 5
    def __to_format(jd: float, fmt: str) -> float:
                      ^
SyntaxError: invalid syntax

I guess this is due to the annotations. Could it be possible to update the code to support also Python>=2.7 ?

Thank you.

Regards,

Luca

The same error from the import statement. Does it seem there is no solution till now?

Well if there is urgent need of the Julian to the Gregorian date conversion, a gist could be possibly referred: https://gist.github.com/jiffyclub/1294443#file-jdutil-py.
