Question

I am trying to create a deque of strings, but when I add a string to the deque it always breaks the string up into individual characters. Here is my code so far:

from collections import deque

my_string = "test"
my_queue = deque(my_string)

print my_queue

The output I get is:

deque(['t', 'e', 's', 't'])

I would like the output to be:

deque(['test'])

Any thoughts?

The deque constructor takes an iterable as a parameter, if you just give the string to it, it will interpret it as a sequence of characters.

In order to do what you want you should wrap your string into a list:

your_string = 'string'
wrap_list = [your_string]
#Now create the deque
d = deque(wrap_list)

Of course you can do everything in one step:

your_string = 'string'
d = deque([your_string])
