在开发或者在github上clone python项目时，我们经常能看到他们工程的根目录下有一个requirements.txt文件，并且在Readme中介绍使用前需要运行一些命令 这个时什么意思呢？ 开发者希望我们能快速配置项目所需要的环境，所以我们需要这个很重要的文件 该
Returns the number of totatives of num Parameters: num – Integer for which number of totatives are needed. Returns: Number of totatives of num Note A totative of an integer num is any integer i such that, 0 < i < n and GCD(i,num) == 1. Uses Euler’s totient function. 这个...

Euler Project question 34 in python way # 145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145. # Find the sum of all numbers which are equal to the sum of the factorial of their digits. # Note: as 1! = 1 and 2! = 2 are not sums they are not included...
I will soon show that the sum of this series to be approximately 1.644934066842264364; and from multiplying this number by six, and then taking the square root, the number 3.141592653589793238 is indeed produced, which expresses the perimeter of a circle whose diameter is 1. Following again the ...
