repr is a Python-thing and it's main feature, I guess, is eval(repr(object)) == object cf. below. So e.g. In [1]: import numpy as np In [2]: repr(np.array([1,2,3])) Out[2]: 'array([1, 2, 3])' In [3]: str(np.array([1,2,3])) Out[3]: '[1 2 3]' I'm not sure convinced that repr is necessarily better, tho. Here's the docstrings. In [4]: str? Type: type String Form:<class 'str'> Namespace: Python builtin Docstring: str(object='') -> str str(bytes_or_buffer[, encoding[, errors]]) -> str Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to 'strict'. In [5]: ?repr Type: builtin_function_or_method String Form:<built-in function repr> Namespace: Python builtin Docstring: repr(object) -> string Return the canonical string representation of the object. For most object types, eval(repr(object)) == object. –Rasmus -- Got mashed potatoes. Ain't got no T-Bone. No T-Bone
