msg = 'afdssav'
MYQ = deque(msg)
MYPQ.append('asdf')
Here I am trying to create a deque of strings, however when I pop elements or try to read elements from it using Python 2.7 I get char by char instead.
How can I make it such that it would return the strings the same way I insert them?
i.e. I want MYQ[1] to be 'asdf' and MYQ.pop() to return msg.
Probably like this:
MYQ = deque([msg])
Demo:
In [1]: from collections import deque
In [2]: msg = 'afdssav'
In [3]: myq = deque([msg])
In [4]: myq.append('asdf')
In [5]: myq
Out[5]: deque(['afdssav', 'asdf'])
The call signature of deque is:
deque([iterable[, maxlen]]) --> deque object
Strings are iterable, but when you iterate over a string, you get single characters. Hence the behavior you see:
In [7]: deque(msg)
Out[7]: deque(['a', 'f', 'd', 's', 's', 'a', 'v'])
You want to give deque an iterable that would produce the entire string.
