In this example you will learn to create a simple calculator that can add, subtract, multiply or divide depending upon the input from the user.
Sample Solution: Python Code: frommathimportsqrtprint('Pythagorean theorem calculator! Calculate your triangle sides.')print('Assume the sides are a, b, c and c is the hypotenuse (the side opposite the right angle')formula=input('Which side (a, b, c) do you wish to calculate? side> '...
In interactive mode, the last printed expression is assigned to the variable _. This means that when you are using Python as a desk calculator, it is somewhat easier to continue calculations, 在交互模式中,最后一个写出的表达式被赋值给_. 这意味着当你把Python作为台式计算机(desk calculator)来使用...
https://leetcode-cn.com/problems/basic-calculator/ 实现一个基本的计算器来计算一个简单的字符串表达式的值。 字符串表达式可以包含左括号 ( ,右括号 ),加号 + ,减号 -,非负整数和空格 。 示例1: 输入: "1 + 1" 输出: 2 示例2: 输入: " 2-1 + 2 " 输出: 3 示例3: 输入: "(1+(4+5+2...
右键单击该类的背景,选择「Go To and Test」。 在主菜单中吗,选择 Navigate → Test。 选择「Create New Test…」,得到以下窗口: Target directory、Test file name 和 Test class name 这三项均保留默认设置。选中上图中两种需要测试的方法并点击 OK。好了!PyCharm 自动创建文件 test_calculator.py,并在其中...
3.3 划分正负地形 Raster Calculator 提取地形差值栅格中的负地形,结果为二值化图像:地形差值高于阈值的部分为正地形(0),低于阈值的部分为负地形(1)。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 outDiff = temp_dir + "DEM_Diff.tif" outNeg = output_dir + "Negative.tif" expression = "A<=...
首先我们创建一个calculator.py模块 ''' 测试模块 ''' def add(a, b): return a + b 然后我们再创建一个add_test.py源代码文件引用该模块。 import calculator if __name__ == '__main__': print(calculate.add(1, 2)) 注意: 我们使用import是导入一个模块,import后面跟的是模块名,其实就是没有...
