It's a ValueError, so the problem is with the value. I suppose
"invalid notation" might work, but since the definition of what's
acceptable to the int() constructor is the same as for a Python
literal, it's not wrong to use that word.
However, if you want to change the wording, I'd be more inclined to
synchronize it with float():
>>> float("a")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: could not convert string to float: 'a'
