今天，小编继续带着各人一路做做有关Python的操练题。

Today, Xiaobian continues to lead us to do exercises on Python.

标题问题：将一个正整数合成量因数。例如：输入90,打印出90=2*3*3*5。

法式阐发：对n停止合成量因数，应先找到一个最小的量数k，然后按下述步调完成：(1)若是那个量数恰等于n，则申明合成量因数的过程已经完毕，打印出即可。(2)若是n<>k，但n能被k整除，则应打印出k的值，并用n除以k的商,做为新的正整数你n,反复施行第一步。(3)若是n不克不及被k整除，则用k+1做为k的值,反复施行第一步。

法式源代码：

Title: Divide a positive integer into prime factors. For example, enter 90 and print 90=2 * 3 * 3 * 5.

Program analysis: To decompose the prime factor of n, first find a minimum prime number k, and then complete the following steps:

(1) If the prime number is exactly equal to n, it means that the process of decomposing the prime factor is over. Print it out.

(2) If n<>k, but n can be divided by k, the value of k should be printed out, and the quotient of n divided by k should be used as a new positive integer, you n, and rePEat the first step.

(3) If n cannot be divided by k, use k+1 as the value of k and repeat the first step.

Program source code:

成果如下：

The results are as follows:

标题问题：操纵前提运算符的嵌套来完成此题：进修成就>=90分的同窗用A暗示，60-89分之间的用B暗示，60分以下的用C暗示。

法式阐发：法式阐发：(a>b) ? a:b 那是前提运算符的根本例子。

法式源代码：

Question: Use the nesting of conditional operators to complete this question: students with grades>=90 are represented by A, students with grades between 60 and 89 are represented by B, and students with grades below 60 are represented by C.

Program analysis: program analysis: (a>b)? a: B This is a basic example of conditional operators.

Program source code:

成果如下：

The results are as follows:

标题问题：一个数若是刚好等于它的因子之和，那个数就称为"完数"。例如6=1＋2＋3.编程找出1000以内的所有完数。

法式源代码：

Title: If a number is exactly equal to the sum of its factors, the number is called "perfect". For example, 6=1+2+3. Program to find all the completions within 1000.
