set & random.choice question

[stevecanfield]

I want to do something like this:

from random import choice
x = set(("jenny", "jacqui", "claire", "chris", "tracy"))
somebody = random.choice(x)

but I bet a "TypeError: unindexable object" error. Any suggestions for
an elegant workaround?

I'm using set because I want to know that I have a collection of unique
objects.

I want to do something like this:

from random import choice
x = set(("jenny", "jacqui", "claire", "chris", "tracy"))
somebody = random.choice(x)

import random
x = set(("jenny", "jacqui", "claire", "chris", "tracy"))
somebody = random.choice(list(x))

You must turn back it into a list, set has no notion of indexing

Hello,

I want to do something like this:

from random import choice
x = set(("jenny", "jacqui", "claire", "chris", "tracy"))
somebody = random.choice(x)

but I bet a "TypeError: unindexable object" error. Any suggestions for
an elegant workaround?

What about somebody = random.choice(list(x)) ?

import random

x = set(("jenny", "jacqui", "claire", "chris", "tracy"))


def draw_from_set(a_set):
random_index = random.randint(0, len(x) - 1)

for i, name in enumerate(x):
if i == random_index:
return name

somebody = draw_from_set(x)

print somebody


Bye,

Oh duh.

Thanks for pointing out the obvious without mocking...
