python每日一函式 - divmod數字處理函式

divmod(a,b)函式

中文說明：

divmod(a,b)方法返回的是a//b（除法取整）以及a對b的餘數

返回結果型別為tuple

引數：

a,b可以為數字（包括複數）

版本：

在python2.3版本之前不允許處理複數，這個大家要注意一下

英文說明：

Take two (non complex) numbers as arguments and return a pair of numbers consisting of their quotient and remainder when using long division. With mixed operand types, the rules for binary arithmetic operators apply. For plain and long integers, the result is the same as (a // b, a % b). For floating point numbers the result is (q, a % b), where q is usually math.floor(a / b) but may be 1 less than that. In any case q * b + a % b is very close to a, if a % b is non-zero it has the same sign as b, and 0 <= abs(a % b) < abs(b).

Changed in version 2.3: Using divmod() with complex numbers is deprecated.

python程式碼例項：

>>> divmod(9,2)
(4, 1)
>>> divmod(11,3)
(3, 2)
>>> divmod(1+2j,1+0.5j)
((1+0j), 1.5j)
