Python yield returns characters instead of string from single-element tuple

Question

I'm using yield to process each element of a list. However, if the tuple only has a single string element, yield returns the characters of the string, instead of the whole string:

self.commands = ("command1")
...
for command in self.commands:
        yield command            # returns 'c' not 'command1'

how can i fix this?

Thanks

Answer 1

A tuple having only 1 element should be written with a trailing comma.

self.commands = ("command1",)

Answer 2

self.commands = ["command1"]

You never told the loop that you had a list, so it's treating the string as the sequence.

edit: or you could just fix the tuple, as recommended ... I assumed you'd want to use a list instead of a tuple.
