Factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 (denoted as 6!) is1*2*3*4*5*6 = 720. Example of a recursive function deffactorial(x):"""This is a recursive function to find the factorial of an integer"""ifx ==...
不过要记住,加法只能在两个列表之间进行,而乘法必须在列表和任何整数之间进行,如下面的例子所示: >>>even = [0,2,4,6,8]>>>odd = [1,3,5,7,9]>>>number = even + odd>>>number [0,1,2,3,4,5,6,7,8,9] >>>["john"] *3['john','john','john'] 在第一个例子中,我们使用加法运算...
