A parser may always use the same base, a callback may need access to one application object, or a formatting function may use a fixed prefix throughout one subsystem.</p> <p>Python&rsquo;s <code>functools.partial()</code> can turn such a general callable into a more focused callable by binding some arguments in advance. The result remains callable, so it can be passed to APIs that expect a function-like object without introducing a wrapper function solely to carry configuration.</p>
