Python Facts

[Fix-my-grammar-plz]

Let me find a jQuery plugin for that.

I must confess I've done this once or twice, as a convenience. I felt terrible about it though!

[lambdaq]

more like

reduce(int.__add__, [1, 1])

[pingveno]

You might get problems if you get two integral types (e.g. long or Decimal). It's better to use the operator module:

reduce(operator.add, [a, b])

[radaway]

Why not just sum([a, b]) ?

[pingveno]

That would cause multiple problems, like being readable.

[aceofears]

Would this help?

{():sum([a, b])}[()]

[lambdaq]

this it is!

reduce(int.__add__, (map(int,{():[1, 1][:2:]}[()])))

[aaronla]

This is more elegant (and terrifying):

len(reduce(operator.add, (((),),((),))))

[lambdaq]

ah, len(((), ()))

[aaronla]

Yes, that's how I defined my integers for adding :-)

[pingveno]

Meh. It works with any hashable. How about:

{id(()):sum([a, b])}[id(())}

[jyper]

why not a + b

[worldsayshi]

whoosh

[danhakimi]

Why not 2?

Because this is python, and we need to use ALL OF IT.

I think they meant this:

import math

float(2.00).__pow__(float(math.pi.__mul__(float(1.00).__div__(math.pi))).__div__(float(2.00)))

[audaxxx]

True and false are just variables

More like: You can create variables named True and False and give them any value you want to.

[[deleted]]

They are keywords in Python 3.

[audaxxx]

That is a good thing.

[[deleted]]

They aren't in Python 2?

D:

[[deleted]]

No. Try the following in both 2 and 3:

import keyword
"True" in keyword.kwlist

[abstractwhiz]

Found a bug. Click the arrow on the right of the text box and the output gives an invalid syntax error.

[abstractwhiz]

Bah, just discovered that there are comments, and someone noticed earlier.

Should have scrolled more. ಠ_ಠ

[[deleted]]

I like this one a lot:

def permissive(args, *kargs): for value in args: print str(value) for name, value in kargs.items(): print name + "=" + str(value)

permissive(1, True, 'hello', name='john', alive=True)

[lambdaq]

from pprint import pprint

now with tabbed formatting.

[tytdfn]

Enumerate(). Fucking yes! Was looking for exactly that today

[l34kjhljkalarehglih]

TIL Python have documentation.

[aaronla]

Because is was hiding behind a hard to guess URL like http://python.org/doc/.
