Here is an example, of how to reverse a tuple: a=(1,2,3)reverse_tuple=tuple(reversed(a))print(reverse_tuple) Output: (3,2,1) In the example above, we first passed the tuple to the built-in reversed() function. So, it returns an reverse iterable object then we passed it back t...

-- 加减乘除 -- 进行运算时,运算符两边都要各留一个空格,这是python的规范 >>> 1 + 1 2 >>> 2 - 1 1 >>> 2 * 3 6 >>> 4 // 2 2 >>> 5 // 2 2 >>> 5 / 2 2.5 -- 取模 - 类似取余数 -- 公式: a%b = a - (a//b)*b ,当两个数中有负数存在时,结果会有点不一样...
stack and crashing Python. The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a ...
