Determine if 2 lists have the same elements, regardless of order? [duplicate]
...
You can simply check whether the multisets with the elements of x and y are equal:
import collections
collections.Counter(x) == collections.Counter(y)
This requires the elements to be hashable; runtime will be in O(n), where n is the size of the lists.
If the elements are also unique,...
How to check if variable is string with python 2 and 3 compatibility
I'm aware that I can use: isinstance(x, str) in python-3.x but I need to check if something is a string in python-2.x as well. Will isinstance(x, str) work as expected in python-2.x? Or will I need to check the version and use isinstance(x, basestr) ?

Duplicates are resolved in favor of the value in x; for example

How can I represent an infinite number in Python?
...rt math
test = math.inf
And then:
test > 1
test > 10000
test > x
Will always be true. Unless of course, as pointed out, x is also infinity or "nan" ("not a number").
Additionally (Python 2.x ONLY), in a comparison to Ellipsis, float(inf) is lesser, e.g:
float('inf') < Ellipsis

...imple construct that will do it, by using setdiff:

And a full example. Run this at your own risk - it will remove all variables except x:
x <- 1
y <- 2
z <- 3
ls()
[1] "x" "y" "z"
rm(list=setdiff(ls(), "x"))
ls()
[1] "x"
