This method returns the square root of the given number.ExampleThe following example shows the usage of the Python math.sqrt() method. Here, we are trying to pass different positive values and find their square root using this method.Open Compiler # This will import math module import math ...
The following program returns the square root of a number using math.sqrt() function −Open Compiler # importing math module import math # input number inputNumber = 25 # getting the square root of an input number squareRoot = math.sqrt(inputNumber) # printing the square root of a ...
# All numbers less than 2 are not prime: if num < 2: return False # See if num is divisible by any number up to the square root of num: for i in range(2, int(math.sqrt(num)) + 1): if num % i == 0: return False return True def primeSieve(sieveSize): # Returns a list...
我们可以将该类加载到 Python 3 解释器中,这样我们就可以交互式地使用它。为了做到这一点,将前面提到的类定义保存在一个名为first_class.py的文件中,然后运行python -i first_class.py命令。-i参数告诉 Python运行代码然后转到交互式解释器。以下解释器会话演示了与这个类的基本交互: >>>a = MyFirstClass()>>>...

So in this case, I’ve asked Python to return the value of square root of 10. 让我们做一些更复杂的事情。 Let’s do something a little more sophisticated. 如果我想找出sin pi除以2的值呢? What if I wanted to find out the value of sin pi over 2? 让我们首先提取pi的值,我们知道它是ma...
python中math模块常用的方法整理 ceil:取大于等于x的最小的整数值,如果x是一个整数,则返回x copysign:把y的正负号加到x前面,可以使用0 cos:求x的余弦,x必须是弧度 degrees:把x从弧度转换成角度 e:表示一个常量 exp:返回math.e,也就是2.71828的
