Getting "TypeError: 'type' object is not subscriptable" with arrays

The array module only allows to create array of basic values (characters, integers, floating point numbers).

You cannot create an array of strings with this module.

More information in the documentation here

I believe using a list would more adapted to your needs:

Code

Romanic=['Italian','French','Spanish','Portugese','Romanian']
print('Romanic languages are ', ', '.join(Romanic), '. Want to insert more?', sep='')

Output

Romanic languages are Italian, French, Spanish, Portugese, Romanian. Want to insert more?

There are a number of problems with your code.

First, there is an array module and part of it, there is an array.array class. When you do

from array import *
Romanic=array['str',(...)]

you are treating array.array as an actual array object, instead of a class. Using [] in Python means accessing an element of something, not for initialization. You should be using ():

>>> from array import array
>>>
>>> array['i',(1,2,3)]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable
>>>
>>> array('i',(1,2,3))
array('i', [1, 2, 3])

Now, even if you changed your code to array('str',...), it still wouldn't work, because the 1st argument to the class initialization should be a valid typecode.

https://docs.python.org/3/library/array.html#array.array

class array.array(typecode[, initializer])

A new array whose items are restricted by typecode, and initialized from the optional initializer value, which must be a list, a bytes-like object, or iterable over elements of the appropriate type.

The array module docs has a table for all the typecodes, and you can also get the valid typecodes by:

>>> from array import typecodes
>>> print(typecodes)
bBuhHiIlLqQfd

and 'str' is not in that of valid typecodes. Maybe you are coming from other programming languages that use arrays, but what you seem to need is just a regular list, which in Python is how we represent a mutable "list of things":

>>> Romanic = ['Italian','French','Spanish','Portugese','Romanian']
>>> print('Romanic languages are ', Romanic, 'Want to insert more?')
Romanic languages are  ['Italian', 'French', 'Spanish', 'Portugese', 'Romanian'] Want to insert more?

Lastly, don't use from module import * syntax. See Why is “import *” bad?. It can become confusing, like in this case with an array module and an array class. Import the actual things you need from the module, or use module.something syntax.
