How do I find out if a value is in a deque?

Question

say i have a deque with values [0,3,5,1,5,8]. I want to save all information about the deque including order, but I have to find if the value 5 is in the deque.

What is some pseudo-code that could determine this?

Answer 1

Are you aware of the in operator?

>>> import collections
>>> d = collections.deque([0,3,5,1,5,8])
>>> 5 in d
True
>>> 20 in d
False
