下面是python代码的实现:#输入一个正整数n=int(input("Enteranintegernumber:"))#初始化总和为0total=0#计算阶乘和累加到总和foriinrange(1,n+1):factorial=1forjinrange(1,i+1):factorial*=jtotal+=factorial#输出结果print(f"1!+2!+3!+...+{n}!结果是{total}") 我们理解一下代码的实现思路:1....
When at least one of the operands is a floating-point number, something interesting happens. The result is a floating-point number, except the decimal part is always 0. Here's an example: >>> 7.0 // 3 2.0 How to Compute Modulo (Mod) in Python The modulo operator % allows us to cal...
