编写的一个python小游戏，乌龟吃小鱼：
假设游戏场景范围想（x，y）均为[0,10];游戏生成1只乌龟和10条鱼；他们移动方向均随机；乌龟最大移动能力为2（可为1或2），鱼最大移动能力为1；当移动到场景边缘自动向反方向动；乌龟初始体能为100（上限）；乌龟每移动一次体力消耗1；乌龟与鱼坐标重合，乌龟吃鱼，乌龟体力增20；鱼暂不计体力；当乌龟体力为0或鱼儿数量为0游戏结束(Prepared a python game, the turtle to eat fish:
Assuming that the game scene range is (x, y) both [0, 10]; the game produces one turtle and ten fish; both move in random directions; the turtle has a maximal moving capacity of 2 (which can be 1 or 2) The ability to move to 1; automatically move to the opposite direction when moving to the edge of the scene; turtle initial physical capacity of 100 (upper limit); turtles for each move a physical expenditure 1; turtle and fish coordinates coincide turtle fish, turtle physical augmentation 20; Excluding body strength; when the tortoise is 0 or the number of fish is 0 The game is over)
