This function may also be used as a decorator. Parameters ---------- func : function The function to be deprecated. old_name : str, optional The name of the function to be deprecated. Default is None, in which case the name of `func` is used. new_name : str, optional The new name for the function. Default is None, in which case the deprecation message is that `old_name` is deprecated. If given, the deprecation message is that `old_name` is deprecated and `new_name` should be used instead. message : str, optional Additional explanation of the deprecation. Displayed in the docstring after the warning. Returns ------- old_func : function The deprecated function.

Parameters ---------- object : object or str, optional Input object or name to get information about. If `object` is a numpy object, its docstring is given. If it is a string, available modules are searched for matching objects. If None, information about `info` itself is returned. maxwidth : int, optional Printing width. output : file like object, optional File like object that the output is written to, default is ``stdout``. The object has to be opened in 'w' or 'a' mode. toplevel : str, optional Start search at this level. See Also -------- source, lookfor Notes ----- When used interactively with an object, ``np.info(obj)`` is equivalent to ``help(obj)`` on the Python prompt or ``obj?`` on the IPython prompt. Examples -------- >>> np.info(np.polyval) # doctest: +SKIP polyval(p, x) Evaluate the polynomial p at x. ...

Parameters ---------- object : numpy object Input object. This can be any object (function, class, module, ...). output : file object, optional If `output` not supplied then source code is printed to screen (sys.stdout). File object must be created with either write 'w' or append 'a' modes.

A list of objects that matched the search is displayed, sorted by relevance. All given keywords need to be found in the docstring for it to be returned as a result, but the order does not matter. Parameters ---------- what : str String containing words to look for. module : str or list, optional Name of module(s) whose docstrings to go through. import_modules : bool, optional Whether to import sub-modules in packages. Default is True. regenerate : bool, optional Whether to re-generate the docstring cache. Default is False. output : file-like, optional File-like object to write the output to. If omitted, use a pager. See Also -------- source, info Notes ----- Relevance is determined only roughly, by checking if the keywords occur in the function name, at the start of a docstring, etc. Examples -------- >>> np.lookfor('binary representation') # doctest: +SKIP Search results for 'binary representation' ------------------------------------------ numpy.binary_repr Return the binary representation of the input number as a string. numpy.core.setup_common.long_double_representation Given a binary dump as given by GNU od -b, look for long double numpy.base_repr Return a string representation of a number in the given base system. ... rNrrc3s|]}|kVqdS)Nr).0w)rBrr szlookfor..i)r!classrrcsd}dj|jjjddd|tfddD7}|tfddD7}|t d7}|j|d 7}|jd  d 7}|t| d d 7}|S)Nrr*r\csg|]}|krdqS)r)rr) first_docrr sz.lookfor..relevance..csg|]}|krdqS)r)rr)r"rrrsr[i.rYdii) rlowerstripr9sumr<getcountri)r"Zdocstrkindindexr)kind_relevancewhats)rr"r relevances zlookfor..relevancecs|f|S)Nr)rW)rmrrrrelevance_valuesz lookfor..relevance_value)keyzSearch results for '%s'r5rr4cSsg|]}|jr|jqSr)r)rrErrrrszlookfor..r*rsz %s %szNothing found.rY)rrii)r_lookfor_generate_cacherdrr9itemsallrfsortrr<r_function_signature_research IndexErrorwriteZgetpagerrj)whatrimport_modules regeneraterrfoundr"Z docstringrrrs help_textixZdoclinesrZpagerr)rmrBrrrrrsJ/        c#Csddl}ddlm}|dkr d}t|trXy t|Wntk rJiSXtj|}nt| D] \}}| j$d| |f|fqLWnt| drd} y|j&| }Wnt!k rd}YnX|dk r|| |f|| <qW|S)a Generate docstring cache for given module.
