If you're writing a library, don't modify the process locale. That's
for an application to set, preferably only once at startup. Use some
other library such as ICU:
>>> import icu
>>> lc = icu.Locale.createCanonical('da_DK.utf-8')
>>> lc.getDisplayLanguage()
'Danish'
>>> lc.getDisplayCountry()
'Denmark'
>>> nf = icu.NumberFormat.createInstance(lc)
>>> nf.parse('123.456,14').getDouble()
123456.14
