Powerful human readable version of dir().

Project description

explor

Python object explorer which shows you what you can do with an object.

It takes the output from dir(), checks this and classifies it in a table. With that, you don't have to read the entire output of dir() and visually filter it for the relevant information.

Installation

Install the package:

pip install explor

or

pip install git+git://github.com/Talon24/explore

or

pip install git+https://github.com/Talon24/explore

Example

From this

# Very long line with very specific information, like all the dunder-methods
import datetime
print(dir(datetime.datetime.now()))
['__add__', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rsub__', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', 'astimezone', 'combine', 'ctime', 'date', 'day', 'dst', 'fold', 'fromisocalendar', 'fromisoformat', 'fromordinal', 'fromtimestamp', 'hour', 'isocalendar', 'isoformat', 'isoweekday', 'max', 'microsecond', 'min', 'minute', 'month', 'now', 'replace', 'resolution', 'second', 'strftime', 'strptime', 'time', 'timestamp', 'timetuple', 'timetz', 'today', 'toordinal', 'tzinfo', 'tzname', 'utcfromtimestamp', 'utcnow', 'utcoffset', 'utctimetuple', 'weekday', 'year']

To this

from explor import explore as ex
import datetime

ex(datetime.datetime.now())
  Inherits:
datetime -> date -> object
  Description:
datetime(year, month, day[, hour[, minute[, second[, microsecond[,tzinfo]]]]])

The year, month and day arguments are required. tzinfo may be None, or an
instance of a tzinfo subclass. The remaining arguments may be ints.

Usage

The module's name is explore and it provides a function called explore(). To simplify exploration, i'd recommend aliasing it as something short like ex.

Settings

You can change the style of the table. The DoubleTable is the default, if the text viewer can't handle unicode, then the AsciiTable might be useful. Some examples to change the Table style:

import explor
explor.TABLETYPE = explor.terminaltables.AsciiTable
explor.TABLETYPE = explor.terminaltables.SingleTable
explor.TABLETYPE = explor.terminaltables.DoubleTable
explor.TABLETYPE = explor.terminaltables.GithubFlavoredMarkdownTable

Automatic import

If you have ipython, you can create a file in ~/.ipython/profile_default/startup/ that imports it, it will then be available at the start of ipython.

This can look like this:

from explor import explore as ex
from explor import explore_signature as exs
from explor import explore_object as exo

get_ipython().magic("%autocall 1")  # With this, it's callable without parens; e.g. `ex os.path`

More explanation here.

Limitations

The library won't always work on some builtin objects like print or libraries written in c, e.g. numpy.array.
