Underscore.py is a python port of excellent javascript library underscore.js
From underscore page:
Underscore.js is a utility-belt library for JavaScript that provides support for the usual functional
suspects (each, map, reduce, filter...) without extending any core JavaScript objects.
Clone this repository:
git clone git://github.com/serkanyersen/underscore.py.gitGet into underscore.py directory
cd underscore.pyRun setup script
sudo python setup.py installThat's it
Import underscore to your project
from underscore import _# Dynamically
_(["foo", "bar"]).invoke("upper") # ["FOO", "BAR"]
# or statically
_.filter(["foo", "hello", "bar", "world"], lambda x, *a: len(x) > 3) # ["hello", "world"]
# Do chaining
_([10, 48, 56, 30, 20]).chain().filter(lambda x, *a: x > 20).map(lambda x, *a: x * 2).sortBy().value()
# [60, 96, 112]tmpl = _.template("Name: <% if prefix: %><%= prefix %>. <% endif %><%= name %>\n\
Last Name: <%=lname.upper() %>\n\
<% if email: %>\
E-mail: <%= email %>\n\
<% endif %>")
people = [{
"prefix": "",
"name": "John",
"lname": "Doe",
"email": "johndoe@example.com"
},{
"prefix": "Mr",

Please keep in mind that this is just a port of a javascript library, please don't get started with the "but it's not pythonic" stuff. This library has no intentions to be pythonic, infact it tries to bring same underscore experience from javascript to python
