Return a new partial object which when called will behave like func
called with the positional arguments args and keyword arguments keywords. If
more arguments are supplied to the call, they are appended to args. If
additional keyword arguments are supplied, they extend and override keywords.
Roughly equivalent to:

def partial(func, *args, **keywords):
    def newfunc(*fargs, **fkeywords):
        newkeywords = keywords.copy()
        newkeywords.update(fkeywords)
        return func(*(args + fargs), **newkeywords)
    newfunc.func = func
    newfunc.args = args
    newfunc.keywords = keywords
    return newfunc

functools.wraps(wrapped, assigned=WRAPPER_ASSIGNMENTS, updated=WRAPPER_UPDATES)¶

This is a convenience function for invoking partial(update_wrapper, wrapped=wrapped, assigned=assigned, updated=updated) as a function decorator
when defining a wrapper function. For example:

>>> from functools import wraps
>>> def my_decorator(f):
...     @wraps(f)
...     def wrapper(*args, **kwds):
...         print('Calling decorated function')
...         return f(*args, **kwds)
...     return wrapper
...
>>> @my_decorator
... def example():
...     """Docstring"""
...     print('Called example function')
...
>>> example()
Calling decorated function
Called example function
>>> example.__name__
'example'
>>> example.__doc__
'Docstring'

operator.itemgetter(item[, args...])¶

Return a callable object that fetches item from its operand using the
operand’s __getitem__() method. If multiple items are specified,
returns a tuple of lookup values. Equivalent to:

def itemgetter(*items):
    if len(items) == 1:
        item = items[0]
        def g(obj):
            return obj[item]
    else:
        def g(obj):
            return tuple(obj[item] for item in items)
    return g

Recipe 576925: Caller and Callee

A recipe to find out which function is the caller of the current function.

Python

      import inspect

def callee():
    return inspect.getouterframes(inspect.currentframe())[1][1:4]

def caller():
    return inspect.getouterframes(inspect.currentframe())[2][1:4]
