【Python】Python3中的除法

示例：

import unittest  # 导入unittest这个模块
import math  # 导入math模块


class Test(unittest.TestCase): # 定义一个测试的类，并继承unittest.TestCase这个类
    def testMinus(self): # 定义测试case，要以test开头
        result = 6-5 expect = 1 self.assertEqual(result, expect) # 断言，assertEqual，判断是否相等

    def testdiv1(self): result = 7/2 # 精确除法，返回float expect = 3.5 self.assertEqual(result, expect) def testdiv2(self): result = 7//2  # 去尾取整，返回int expect = 3 self.assertEqual(result, expect) def testdiv3(self): result = math.ceil(7/2) # 向上取整
        expect = 4 self.assertEqual(result, expect) def testdiv4(self): result = math.floor(7/2) # 向下取整
        expect = 3 self.assertEqual(result, expect) def testdiv5(self): result = round(7/2) # 四舍五入取整
        expect = 4 self.assertEqual(result, expect) if __name__ == '__main__': unittest.main() # 运行主函数 

结果：
