PynEntry
A pythonic wrapper for pinentry
Written mostly to practice metaprogramming
credit to mijikai for a working example
Requires pinentry to be installed
convienience methods:

to quickly and simply get a password/pin from a user:

get_pin(description=None, prompt=None, timeout=0, display=None, global_grab=True)

to show and get a confirmation from a user:

get_confirm(description=None, timeout=0, display=None, global_grab=True)

to show a message to a user:

show_message(description=None, timeout=0, display=None, global_grab=True)
PynEntry class
The above methods instance and configure a PynEntry instance wich can be called and configured manually
via attributes
the PynEntry class supports the following attributes:

description: Sets the descriptive text to display
prompt: Sets the text just before the passphrase entry (ex: "PASS:")
title: Sets the window title
ok_text: Sets the text shown in the "OK" button
cancel_text: Sets the text shown in the "Cancel" button
error_text: Sets the text in case of error before reprompt (Cleared after every get_pin() call)
tty_name: Chose the tty to use (set automatically)
tty_type: Change the tty type to use.
locale: Sets the locale to use (set automatically to current os locale)

NOTE: The PynEntry class uses the $PATH variable to find the pinentry executable, you can specify the location of the
executable manually when you initialize like so: PynEntry(executable='/path/to/pinentry')
PynEntry is best used as a context manager to automatically kill the pinentry process when you are done.
Example:
import pynentry
pynentry.show_message('Hello there!')

with pynentry.PynEntry() as p:
p.description = 'Enter a password.\n Choose Wisely!'
p.prompt = 'PASS>'
try:
passwd = p.get_pin()
except pynentry.PinEntryCancelled:
print('Cancelled?! Goodbye.')
exit()
p.ok_text = 'yep!'
p.cancel_text = 'nope!'
p.description = f'CAN YOU CONFIRM YOUR SUPER SECRET PASSWORD IS {passwd}?'
if p.get_confirm():
print(f'password {passwd} saved!')
else:
print(f'Too bad, so sad')
