计算有多少用户输入和这些输入的平均值

Question

试图完成python家庭作业任务，部分程序需要计算其计算的BMI数以及用户写完后这些BMI的平均值'n'。帮助将不胜感激，这就是我现在所拥有的。

y = True

while y:   

weight = float(input("Enter weight in kg:"))
height = float(input("Enter height in m:"))
bmi = weight/(height**2)

if bmi <18:
    print("Your BMI is", bmi, "\nIt indicates you are underweight")
elif bmi >=18 and bmi <=25:
    print("Your BMI is", bmi, "\nIt indicates you are within normal bounds")
elif bmi >25:
    print("Your BMI is", bmi, "\nIt indicates you are overweight")

again = str(input("Another BMI? y/n:"))
if again == "n":
    y = False

Answer 1

在进入 while 循环之前，您需要创建一个空列表 bmi_records。然后只需将新的 BMI 添加到 bmi_records 列表即可。

bmi_records = []
while ....
    bmi = ...
    bmi_records.append(bmi)
    ....

print(f'Average of {len(bmi_records)} BMIs entered: {sum(bmi_records)/len(bmi_records):.1f}')

计算有多少用户输入和这些输入的平均值
