int()是Python的一个内部函数
Python系统帮助里面是这么说的
>>> help ( int )
Help on class int in module __builtin__:
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 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 ( 12.0 )
12 |
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
3

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