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.

>>> np.source(np.interp)                        
In file: /usr/lib/python2.6/dist-packages/numpy/lib/function_base.py
def interp(x, xp, fp, left=None, right=None):

    if isinstance(x, (float, int, number)):
        return compiled_interp([x], xp, fp, left, right).item()
    else:
        return compiled_interp(x, xp, fp, left, right)

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

>>> np.source(np.array)
