numpy.source

numpy.source(object, output=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>) [source]

Print or write to a file the source code for a NumPy object.

The source code is only returned for objects written in Python. Many functions and classes are defined in C and will therefore not return useful information.

Parameters

objectnumpy object

Input object. This can be any object (function, class, module, …).

outputfile 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.

    else:
        return compiled_interp(x, xp, fp, left, right)

The source code is only returned for objects written in Python.
