Deque to string in Python3

In Python2 I was able to do something similar to:

frames = deque(maxlen=xyz)
framesString = ''.join(frames)

In Python3 I get an error.

How should I change it in order to get a string representing the deque object?

Thanks in advance, G.

Solution

  • From Python official documentation, you can use deque like this:

    from collections import deque

# With an infinite length
frames = deque('ytreza')
''.join(frames)
# It will display 'azerty'

# With a maximum length
frames = deque('ytreza', maxlen=3)
''.join(frames)
# It will display 'aze'

# With no input
assert len(deque(maxlen=3)) == 0
''.join(deque(maxlen(3)))
# It will display an empty string

    If content of the deque is bytes, a str conversion should be performed, with an expression generator for example.

    ''.join(str(element) for element in my_deque)
