为什么int(12,16)会报错

[核动力蜗牛Killua]

>>> int (12,16)

Traceback (most recent call last):
  File "<pyshell#41>", line 1, in <module>
    int (12,16)
TypeError: int() can't convert non-string with explicit base

函数int(obj,base = 10)，这样用应该没错的啊？

哪位大大能稍微讲解下

忘记说了，我说的是python

>>> help(int)


class int(object)
 |  int(x[, base]) -> integer
 |  
 |  Convert a string or number to an integer, if possible.  A floating point
 |  argument will be truncated towards zero (this does not include a string
 |  representation of a floating point number!)  When converting a string, use
 |  the optional base.  It is an error to supply a base when converting a
 |  non-string. If the argument is outside the integer range a long object
 |  will be returned instead.


>>> int ('12', 16)
18
>>>

can't convert non-string with explicit base

这不是挺清楚的吗？
