int()是Python的一個(gè)內(nèi)部函數(shù) 

Python系統(tǒng)幫助里面是這么說的

>>> 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()函數(shù)可以將一個(gè)數(shù)轉(zhuǎn)化為整數(shù) 

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

這里有兩個(gè)地方要注意：1）12要以字符串的形式進(jìn)行輸入，如果是帶參數(shù)base的話

2）這里并不是將12轉(zhuǎn)換為16進(jìn)制的數(shù)，而是說12就是一個(gè)16進(jìn)制的數(shù)，int()函數(shù)將其用十進(jìn)制數(shù)表示，如下

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

總結(jié)

以上所述是小編給大家介紹Python中int()函數(shù)的用法淺析，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時(shí)回復(fù)大家的。在此也非常感謝大家對武林站長站網(wǎng)站的支持！
