see is an alternative to dir()
, for Python 2.7 and 3.4+.
It neatly summarises what you can do with an object. Use it to inspect your code or learn new APIs.
Say you have an object which you'd like to know more about:
>>> from datetime import timedelta
Try inspecting the object with see
:
>>> see(timedelta)
isclass + -
* / //
% +obj -obj
< <= ==
!= > >=
abs() bool() dir()
divmod() hash() help()
repr() str() .days
.max .microseconds .min
.resolution .seconds .total_seconds()
Here we can discover some things about it, such as:
- The object is a class.
- You can add something to it with the
+
operator. - It has a
seconds
attribute. - It has a
total_seconds
attribute which is a function.
Compare with the output of dir
:
>>> dir(timedelta)
['__abs__', '__add__', '__bool__', '__class__', '__delattr__', '
__dir__', '__divmod__', '__doc__', '__eq__', '__floordiv__', '__
format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '
__init__', '__init_subclass__', '__le__', '__lt__', '__mod__', '
__mul__', '__ne__', '__neg__', '__new__', '__pos__', '__radd__',
'__rdivmod__', '__reduce__', '__reduce_ex__', '__repr__', '__rf
loordiv__', '__rmod__', '__rmul__', '__rsub__', '__rtruediv__',
'__setattr__', '__sizeof__', '__str__', '__sub__', '__subclassho
ok__', '__truediv__', 'days', 'max', 'microseconds', 'min', 'res
olution', 'seconds', 'total_seconds']
You can filter the results of see
using a wildcard pattern
or a regular expression:
>>> see(timedelta).filter('*sec*')
.microseconds .seconds .total_seconds()
>>> see(timedelta).filter('/^d/')
dir() divmod()
