When using a for loop for a fixed list, type() is only the first letter

Asked by Matt Brown

Hello,

When I use a for loop with a fixed list, when accessing the current item with `entry`, only the first letter of `entry` appears be typed using `type()`.

Is there an issue with type() or an issue with my syntax?

    myListFixed = ("insomuchas")
    for entry in myListFixed:
      type(entry)

Thanks

myListFixed = ("insomuchas")

... just is the list of characters in the given string

myListFixed = ("insomuchas", )

makes a list with 1 string as entry.

Has nothing to do with that problem, but be aware of the restrictions of type() (see docs)
paste() might be the better choice.

Ahh hah! Excellent.

Is there a way to strongly type this is a string array so I don't run into this issue?

Of course, single string was intended as a test.

Thanks RaiMan, that solved my question.

In re to #2, quite obviously a lack of understanding of collections in python. Using a list `()` versus a set `[]` so that redundant entries can be contained therein. Thanks!

Python generally is not strongly typed, hence type is evaluated from context on assignment.
... and variables can change their type at any time.

BTW: ("foo",) is not a list but a tuple and immutable.

The problem: the brackets ( ) syntactically are expression delimiters and the tuple itself is "foo",

a list (mutable) is defined as:
aList = ["foo"]

or
aList = []
aList.append["foo"]

please consult the Python docs or a basic tutorial if you plan to do more complex things.
