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 ...
"" # 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 ...
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...

$ python myprogram.py Python 在语法上是编程语言中独一无二的,因为它使用空白或缩进块来屏蔽代码。像 C 这样的语言用花括号括起了一个代码块,比如一个if语句;Python 使用冒号和缩进来描述块。C 语言中的代码如下所示:if (x==4) { printf("x is equal to four\n"); printf("Nothing more to do ...
