### 今日筆記
1. 九九乘法表
- for loop

for i in range(2, 10):
    for j in range(1, 10):
        print(f'{i} * {j} = {i*j}')
    print('\n') 

- while loop

i = 2
while i <= 9:
    j = 1
    while j <=9:
        print(f'{i} * {j} = {i*j}')
        j = j + 1
    i = i + 1

2. 七九乘法表
- for loop + break

for i in range(2, 10):
    for j in range(1, 10):
        print(f'{i} * {j} = {i*j}')
    print('\n')   
    if i == 7:
       break

- while loop + break

i = 2
while i <= 9:
    j = 1
    while j <=9:
        print(f'{i} * {j} = {i*j}')
        j = j + 1
    if i == 7:
        break
    i = i + 1

3. BMI計算器
- 單一計算

def bmi_calculator_1(weight, height):
    """
    BMI = 體重/身高**2
    weight: int, 體重(以公斤計)
    height: float, 身高(以公尺計)
    """
    bmi_value =  weight / height**2
    return bmi_value    

- 串列計算

def bmi_cal_list(w_list, h_list):
    bmi_output=[]
    for w, h in zip(w_list, h_list):
        bmi = round((w/(h/100)**2), 2)
        bmi_output.append(bmi)
    return bmi_output
