Troubleshooting: ``ugettext()`` incorrectly detects ``python-format`` in strings with percent signs
---------------------------------------------------------------------------------------------------
In some cases, such as strings with a percent sign followed by a space and a
:ref:`string conversion type <old-string-formatting>` (e.g.
``_("10% interest")``), :func:`~django.utils.translation.ugettext` incorrectly
flags strings with ``python-format``.
If you try to compile message files with incorrectly flagged strings, you'll
get an error message like ``number of format specifications in 'msgid' and
'msgstr' does not match`` or ``'msgstr' is not a valid Python format string,
unlike 'msgid'``.
To workaround this, you can escape percent signs by adding a second percent
sign::
from django.utils.translation import ugettext as _
output = _("10%% interest)
Or you can use ``no-python-format`` so that all percent signs are treated as
literals::
# xgettext:no-python-format
output = _("10% interest)
