今天小编带着大家一起做一做Python的经典练习题。

Today, I will take you to do a classic Python exercise.

题目：有四个数字：1、2、3、4，能组成多少个互不相同且无重复数字的三位数？各是多少？

程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去掉不满足条件的排列。

Title: There are four numbers: 1, 2, 3 and 4. How many different three digit numbers can be formed without repetition? How many are each?

Program analysis: the numbers that can be filled in hundreds, tens and ones are 1, 2, 3 and 4. After forming all permutations, remove the permutations that do not meet the conditions.

可以用for in range进行遍历循环，程序源代码如下：

You can use for in range to traverse the loop. The program source code is as follows:

输出结果如下：

The output results are as follows:

题目：企业发放的奖金根据利润提成。利润(I)低于或等于10万元时，奖金可提10%；利润高于10万元，低于20万元时，低于10万元的部分按10%提成，高于10万元的部分，可提成7.5%；20万到40万之间时，高于20万元的部分，可提成5%；40万到60万之间时高于40万元的部分，可提成3%；60万到100万之间时，高于60万元的部分，可提成1.5%，高于100万元时，超过100万元的部分按1%提成，从键盘输入当月利润I，求应发放奖金总数？

程序分析：请利用数轴来分界，定位。

Topic: Bonus paid by enterprises is based on profits. When the profit (I) is less than or equal to 100000 yuan, the bonus can be increased by 10%; If the profit is higher than 100000 yuan and lower than 200000 yuan, 10% of the part below 100000 yuan will be entitled to a royalty, and 7.5% of the part above 100000 yuan will be entitled to a royalty; Between 200000 yuan and 400000 yuan, the part higher than 200000 yuan can be deducted by 5%; For the part higher than 400000 yuan between 400000 and 600000 yuan, 3% can be deducted; Between 600000 yuan and 1 million yuan, the part above 600000 yuan will be entitled to 1.5% of the commission, while the part above 1 million yuan will be entitled to 1% of the commission. Enter the profit I of the current month from the keyboard, and ask for the total amount of bonuses to be paid?

Program analysis: Please use the number axis to divide and locate.

代码如下：

The code is as follows:

运行结果如下：

The operation results are as follows:

我们输入几个利润大致验证一下，结果如下：

We input several profits to roughly verify, and the results are as follows:
