# Python Basic Exercises

Here are some simple exercises I have written while learning Python. The answers to these exercises may not be completely correct for my own reference only!

### [Title 1]

Print a graphic like this

*****
***
*
***
*****

```# for i in range(-2,3):
#     for z in range(3-abs(i)):
#         print(' ',end='')
#     for j in range(2*abs(i)+1):
#         print('*',end='')
#     print(' ')
```

### [Title 2]

Enter three integers and output them once from small to large and from large to small, respectively

```# x=5
# y=1
# z=9
# m=[x,y,z]
# m.sort(reverse=True)#reverse=Ture is to sort list s from large to small
# print(m)
# m.sort()
# print(m)
```

### [Title 3]

Enter the day of the month and year to determine the day of the year

```# x = int(input('Please enter year:'))
# y = int(input('Please enter month:'))
# z = int(input('please enter date:'))
# sum=0
# mouth=[0,31,59,90,120,151,181,212,243,273,304,334]
# if y>0 and y<=12:
#     sum=sum+mouth[y-1]
# if z>0 and z<=31:
#     sum=sum+z
# if x%4==0 and x%100!=0 or x%400==0:
#     sum=sum+1
# print(sum)
```

### [Title IV]

An integer, which is a complete square number after adding 100, and 168 is a complete square number. What is the number, please?

```# import math
# while b<=100000:
#     c=b+100
#     d=int((math.sqrt(c)))
#     f=b+268
#     e=int((math.sqrt(f)))
#     if c==d**2 and f==e**2:
#         print(b)
#     b+=1```

### [Title 5]

```The bonus awarded by the enterprise shall be based on profit.If the profit (I) is less than or equal to 100,000 yuan, the bonus may be increased by 10%; the profit is high
When RMB 100,000 is less than RMB 200,000, the part less than RMB 100,000 will be deducted by 10%, and the part higher than RMB 100,000 will be deducted.
7.5%; between 200,000 and 400,000, 5% of the higher than 200,000 yuan can be deducted; between 400,000 and 600,000, it is higher than
The part of 400,000 yuan may be credited 3%; between 600,000 and 1,000,000 yuan, the part above 600,000 yuan may be credited 1.5%, which is higher than
When 1 million yuan is added, the part exceeding 1 million yuan is deducted by 1%. Enter profit I for the month from the keyboard and ask for the total bonus?```
```# bonus1 = 100000 * 0.1
# bonus2 = bonus1 + 100000 * 0.500075
# bonus4 = bonus2 + 200000 * 0.5
# bonus6 = bonus4 + 200000 * 0.3
# bonus10 = bonus6 + 400000 * 0.15
#
# i = int(input('input gain:\n'))
# if i <= 100000:
#     bonus = i * 0.1
# elif i <= 200000:
#     bonus = bonus1 + (i - 100000) * 0.075
# elif i <= 400000:
#     bonus = bonus2 + (i - 200000) * 0.05
# elif i <= 600000:
#     bonus = bonus4 + (i - 400000) * 0.03
# elif i <= 1000000:
#     bonus = bonus6 + (i - 600000) * 0.015
# else:
#     bonus = bonus10 + (i - 1000000) * 0.01
# print ('bonus = ',bonus)
```
