The square root of zero is: 0.0 ExampleIf we pass a complex number to the sqrt() method, it returns a TypeError.Here we are creating an object 'x' with the value '6 + 4j'. Then we are passing this num as an argument to the method....
importmath# 计算平方根sqrt_value=math.sqrt(25)print("Square Root:",sqrt_value)# 计算正弦值sin_...
The math module also comes with several functions, or methods. 让我们试试平方根函数。 Let’s try out the square root function. 要使用它,我键入math.sqrt,输入参数是我希望平方根取的数字。 To use that, I type math.sqrt and the input argument is the number that I want the square root to ...
每当我们想在Python程序中使用包或模块时,首先我们需要使其可访问。 因此,我们需要将该程序包或模块导入程序中。 Suppose, we have a number. we want to print it’s square root. So if we write this below program, it should work fine. 假设我们有一个数字。 我们要打印它的平方根。 因此,如果我们在...
"" # Handle special cases: if number < 2: return False elif number == 2: return True # Try to evenly divide number by all numbers from 2 up to number's # square root. for i in range(2, int(math.sqrt(number)) + 1): if number % i == 0: return False return True # If ...
Print the resultant square root of an input number. Example 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 = mat...
Calculate the Square Root The square root of a number is a value that, when multiplied by itself, gives the number. You can use math.sqrt() to find the square root of any positive real number (integer or decimal). The return value is always a float value. The function will throw a ...
Raising a number to the power of 0.5 is the same as taking the square root, but notice that even though the square root of 9 is an integer, Python returns the float 3.0.For positive operands, the ** operator returns an int if both operands are integers and a float if any one of ...
功能描述:可以通过注释的方式在题头中简要描述程序的功能,例如# Description: This program calculates the square root of a given number。这样可以帮助其他开发者理解代码的主要功能。 请注意,在Python中题头并非强制要求,在一些简单的脚本或示例代码中,可能并不包含题头。但对于大多数项目或代码文件,良好的题头可以提...
# 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 (i, num / i) return None # No factors exist for num; num must be prime. 如果我们编写一个公钥密码破解程序,我们可以只调用这个函数...
