I can't find these via web serch

thank you in advance,

str2func: getattr(some_module, 'f')
func2str: f.__name__
ischar: isinstance(x, basestring) and len(x) == 1
isfunc: callable(x) # is most likely to be what you want

You won't find exact equivalents. But, the same functionality is
available. Perhaps you would like to show us what you are trying to do
in Python.

Python's eval has some similarity with str2func

Python's repr() or str() has some similarity with func2str

ischar(A) is similiar to isinstance(A, str)

isfunc is similiar to callable

-Travis

P.S. (if you are using NumPy, then there are other possibilities as well.

Thank you
(however in MATLAB ischar is the same as isstr)
but what if I don't know the name of module?
I.e. I have

def myfunc(param): ...
#where param can be both funcName or a function, and I want to obtain
both name and func, something like
if isinstance(param, basestring):
func, funcName = <something>, param
else: func, funcName = param, param.__name__
what should I type instead of <something>?

Right, sorry.

both name and func, something like

func, funcName = <something>, param
else: func, funcName = param, param.__name__

globals()[param] (I assume you don't want a local function, should one exist?)
