Use `raise Exception from None` in `except` clauses to suppress messages

Do you know how to make this compatible with Python 2.7? I get the error

  File "/home/travis/build/pseewald/fprettify/fprettify/__init__.py", line 241
    raise FprettifyParseException("non-standard expression involving + or -",'',0) from None

Well, python2 does not support the syntax..

Maybe your system is set up to work in Python2 and neither a portable Python3 on a USB drive (e.g., WinPython (1)), nor a separate minimal installation of, say Miniconda (2) suits your needs. If the number of .f95 (or higher) files is manageable and their content is not confidential, you may consider to prettify them on repl.it as an installation free alternative. Then all you need is a web browser connected to them.

Once registered, e.g. via GitHub credentials

choose a bash session
drop the files to work on in the left hand files pane
install fprettify, e.g. by pip install fprettify in the right hand terminal offered by repl.it
run fprettify from the right hand terminal in a pattern of fprettify example.f95
retrieve the prettified files either individually, or as a .zip archive from the left hand column (the .zip option is within the menu by tipping the three vertical dots of the file pane).

This is possible because one of the programming languages installed on this server is Python 3.8. (By an explicit call of python2, the bash session either starts Python 2.7.17, or 2.7.18.)

Side note: there is an elder gfortran-7 installed there, too. Thus, depending on the code's instructions it is possible to run gfortran test.f95 -o executable followed by ./executable on the spot, too.

This is not the problem - I decided to make fprettify compatible with Python 2.7 as long as many systems come with Python 2.7 as the default Python version. This has probably changed in the mean time as Python 2 reaches end of life this year, and dropping Python 2 support is probably the way to go.
