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
-
- 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.
Examples
>>> 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): """.... (full docstring printed)""" 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) Not available for this object.
