python36 递归计算指定数字的阶乘

# 递归： 只举个简单的例子吧，计算：指定数字的阶乘 def factorial(num):     if num == 1:         return 1     else:         return num * factorial(num - 1)     print(factorial(2))  # 2*1 print(factorial(3))  # 3*2*1 print(factorial(4))  # 4* 3* 2*1 print(factorial(5))  # 5*4*3*2*1 print(factorial(10)) ''' 2 6 24 120 3628800   Process finished with exit code 0 '''
