### sort and search

# global

val={}

# sort func_

def sort():
for x in range(int(len(val))-1):
for y in range(x+1,int(len(val))):
# print(y)
if val[x]>val[y]:
tmp=val[x]
val[x]=val[y]
val[y]=tmp
print(val)

#search func_

def search(g, l, r):
mid=int((l+r)/2)

if l>r:
print('err0r')
return

elif val[mid] is g:
print(f'index:{mid}')
return

elif val[mid]<g:
search(g, mid+1, r)

else:
search(g, l, mid-1)

# main
n=int(input('input how many numbers in the array?\n> '))
print('input')
for i in range(n):
val[i]=int(input(f'{i+1}. '))

sort()

m=int(input('input how many numbers need to search?\n> '))
print('input')

for i in range(m):
tmp=int(input(f'{m}. '))
search(tmp, 0, int(len(val))-1)

name=str(input('Hello sir, Please input ur name\n> '))
print(f'Hello, {name}. Welcome back!')

### 1110928

- Python 變數概念

> 概念:類似C++ `auto` 型態
> 
> 命名法則:同C++

a=int(input('Input the first number.\n> '))
b=int(input('Input the first number.\n> '))

print(f'{a} + {b} = {a + b}')
print(f'{a} - {b} = {a - b}')
print(f'{a} * {b} = {a * b}')
print(f'{a} / {b} = {a / b}')
print(f'{a} % {b} = {a % b}')

- operator概念

  - arithmetic operator

  > \+ : 加法
  > \- : 減法
  > \* : 乘法
  > \/ : 除法
  > \% : 模除

### 1111012

- 四捨五入
  - module: `round`

print(round(2/3))

      
  - 實作:`temperature convert`

temperature= input(('Input the temperature (included °C or °F or K)\n> '))
temperature= temperature.split(' ')
temperature[1]= temperature[1].lower()
# print(temperature)

if temperature[1] == '°c':
# print('C')
temperature.insert(2, round(int(temperature[0])))

elif temperature[1] == '°k':
# print('F')
temperature.insert(2, round((int(temperature[0])-32)*5/9))

elif temperature[1] == 'k':
# print('K')
temperature.insert(2, round(int(temperature[0])-273.15))

else:
print('3rr0r')

temperature.insert(3, round(temperature[2]*9/5+32))
temperature.insert(4, round(temperature[2]+273.15))

print(temperature)

- compare operator

a= int(input('Input value of a:\n> '))
b= int(input('Input value of b:\n> '))

print(f'a == b is {a == b}')
print(f'a != b is {a != b}')
print(f'a >= b is {a >= b}')
print(f'a > b is {a > b}')
print(f'a <= b is {a <= b}')
print(f'a < b is {a < b}')

### 111019

- 優先度概念
  - 算數運算子 (arithmetic operator) > 比較運算子(comparison operator) > 邏輯運算子(logical operator)
  - [參考文章](https://magicjackting.pixnet.net/blog/post/70902861)

print(1/2 > 1 and 1 != 1)

print(True or False or True)

print(1 < 1 and 5 == 6 or 7 > 7)

> result:
>
> \> False
>
> \> True
>
> \> False


### 1111102

num=int(input('Input a number\n> '))

print(f'{num} is 3\'s mutiple')

### 1111109

score=int(input('Input your score'))
if 100>=score>=90:
print('優等')
elif 90>score>=80:
print('甲等')
elif 80>score>=70:
print('乙等')
elif 70>score>=60:
print('丙等')
