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 be taken of. 在本例中,我要求Python返回10的平方根值。 So in this case, I’ve aske...
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...
The square root of a number X is a number y such that y*y =X We cannot use this to find the square root of a particular instance of X. Imperative knowledge Here is a "recipe" for deducing a square root of a number X-attributed to Heron of Alexandria in the first century AD ...
第17 行开始了实现试除法算法的for循环。它还使用math.sqrt()得到num的平方根,并使用返回的浮点值来设置我们将测试的整数范围的上限。 # 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 ...
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 ValueError if you try to...
