===== sententcia with =====
[[https://docs.python.org/3/reference/compound_stmts.html#the-with-statement]]

Cuando se abren recursos como conexiones remotas o archivos, que necesitan un proceso de limpieza después de usarlos, ''with'' se ocupa de todo ello (siempre que el objeto implemente los métodos mágicos necesarios)
<code python>

#The following code:

with EXPRESSION as TARGET:
    SUITE

#is semantically equivalent to:

manager = (EXPRESSION)
enter = type(manager).__enter__
exit = type(manager).__exit__
value = enter(manager)
hit_except = False

try:
    TARGET = value
    SUITE
except:
    hit_except = True
    if not exit(manager, *sys.exc_info()):
        raise
finally:
    if not hit_except:
        exit(manager, None, None, None)
