int()是Python的一个内部函数
Python系统帮助里面是这么说的
>>>

| 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

-
string. If base
is
zero, the proper base
is
guessed based on the

is
outside the integer
range
a

long
object
will be returned instead.

int()函数可以将一个数转化为整数
>>>
int
(
'12'
,
16
)
18
|
这里有两个地方要注意:1)12要以字符串的形式进行输入,如果是带参数base的话
2)这里并不是将12转换为16进制的数,而是说12就是一个16进制的数,int()函数将其用十进制数表示,如下
1
2

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