Can you provide a little bit more context to your problem (i.e. more code)?
This TypeError message is very generic and it tells you that "st" is an
integer. When it says that it is "*not callable*" it means that you cannot
write " st(something) ". For example, this recreate the same error message:
sage: st = 42
sage: st([1,2,3])
Traceback (most recent call last):
...
TypeError: 'sage.rings.integer.Integer' object is not callable
