int()是Python的一個內部函數
Python系統幫助里面是這么說的

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 base
is
zero, the proper base
is
guessed based on the
| string content. If the argument
is
outside the integer
range
a
|
long
object
will be returned instead.

int()函數可以將一個數轉化為整數
>>>
int
(
'12'
,
16
)
18

這里有兩個地方要注意:1)12要以字符串的形式進行輸入,如果是帶參數base的話
2)這里並不是將12轉換為16進制的數,而是說12就是一個16進制的數,int()函數將其用十進制數表示,如下
1
2

>>>
int
(
'0xa'
,
16
)
10
>>>
int
(
'10'
,
8
)
