How can I create an array of Unicode characters in Python?

Question

I am using Repl.it.

import array as arr

my_array = arr.array("u", [u"3", u"6", u"9", u"12"])
print(my_array)
print(type(my_array))
print(type(my_array[0]))

The above source code produces the following error:

Traceback (most recent call last):
  File "main.py", line 3, in <module>
    my_array = arr.array("u", [u"3", u"6", u"9", u"12"])
TypeError: array item must be unicode character

Why the source code isn't working?

Which version of python you are using?

I mean your sys.version?

Array type "u" corresponds to a single Unicode character. The initializer contains a two-character item u"12". Perhaps you want something like:

arr.array("u", [u"3", u"6", u"9", u"1", u"2"])

It can also be initialized more simply as my_array = arr.array('u','36912').

@MarkTolonen Yes. I assumed OP has to use a list since it was in the question

It was just a general comment. The OP may not know it is easier to type.
