I don't see a picture.  The mailing list probably does not accept
attachments.  (You don't need a picture anyway.)

The int() constructor takes a base parameter whose default value is 10.
If you specify base=0, it will accept binary, octal, and hexadecimal
numbers in addition to decimal.  All this is explained in the link I
gave you.

'42' is a valid literal for int().  'y' is not.

What value did you expect int('y') to give you?

Perhaps you have a variable named 'y' containing a string?  If so, you
might want something like int(y) or int(f{'y'}), but int('y') passes the
literal string 'y', which has nothing to do with a variable of that
name.

Do you mean "str to int"?

You don't.  If you don't specify the base, it defaults to 10.

You can add a signature to all your messages if you like, but it will be
very helpful if you introduce it with a line consisting of "-- ", as
I've done here.

It would also be very helpful if you introduce line breaks into your
message, particularly before and after any included code.  The
formatting made your message difficult to read.
