Python中的BMI索引

我需要帮助为我的家庭作业编写代码，我感觉我可能遗漏了一些东西，非常感谢您的帮助/反馈

诚恳 梅雷迪斯

def calc_BMI():
   weight=requestNumber("Enter weight (kg)")
   height=requestNumber("Enter Height (meters)")
   bmi=(weight/(height*height))
   print 'Your BMI in %2f' % bmi
   if bmi=<15
      print('Your weight status is Very Severely Underweight')    
   elif bmi>=15.0 and bmi<=16.0
    print ('Your weight status is Severely Underweight')
   elif bmi>=16.0 and bmi<=18.5
    print ('Your weight status is Underweight')
   elif bmi>= 18.5 and bmi <=25       
    print('Your weight staus is Normal')
   elif bmi >=25 and bmi <=30
    print ('Your weight status is Overweight')
   elif bmi>=30 and bmi <=35
    print ('Your weight status is Moderately Obese')
   elif bmi >=35 and bmi<=40
    print ('Your weight status is Severely Obese')
   elif bmi <=40 
    print ('Your weight status is Very Severely Obese') 

def calc_BMI（）：
重量=请求数量（“输入重量（kg）”）
高度=请求编号（“输入高度（米）”）
体重指数=（体重/（身高*身高））
在%2f“%BMI”中打印“您的体重指数”
如果bmi=15.0，bmi=16.0，bmi=18.5，bmi=25，bmi=30，bmi=35，bmi您的代码存在多个问题：

将在此处列出它们：

requestNumber
不是python中的方法。导入具有此方法的库。或者使用默认的
input
方法
weight=requestNumber（“输入重量（kg）”）

取而代之

weight=输入（“输入重量（kg）”）

在if条件结束时，您应该有一个“：”
例如：
如果bmi您的代码中有几个错误，我已经对这些问题进行了评论：

def calc_BMI():
   weight=int(input("Enter weight (kg)"))#make sure value taken is int
   height=float(input("Enter Height (meters)"))#make sure value taken is float
   bmi=(weight/(height**2))#use the power operator for squaring instead
   print ('Your BMI in %2f' % bmi)
   if bmi <= 15 :#colon eexpected
         print('Your weight status is Very Severely Underweight')
   elif bmi>=15.0 and bmi<=16.0:#colon eexpected
        print ('Your weight status is Severely Underweight')
   elif bmi>=16.0 and bmi<=18.5:#colon eexpected
        print ('Your weight status is Underweight')
   elif bmi>= 18.5 and bmi <=25 :#colon eexpected
        print('Your weight staus is Normal')
   elif bmi >=25 and bmi <=30:#colon eexpected
        print ('Your weight status is Overweight')
   elif bmi>=30 and bmi <=35:#colon eexpected
        print ('Your weight status is Moderately Obese')
   elif bmi >=35 and bmi<=40:#colon eexpected
        print ('Your weight status is Severely Obese')
   else:#no need for a elif,rather use else for the rest
       print('Your weight status is Very Severely Obese')
calc_BMI()# call the function to run 

def calc_BMI（）：
重量=整数（输入（“输入重量（kg）”）#确保取的值为整数
高度=浮动（输入（“输入高度（米）”）#确保取的值为浮动
bmi=（体重/（身高**2））#使用幂运算符进行平方运算
打印（“%2f”%BMI）中的您的体重指数
如果bmi=15.0，bmi=16.0，bmi=18.5，bmi=25，bmi=30，bmi=35，bmi=35，则最后的
elif
应具有
bmi>=40
。但是，你到底要问什么？在你的<代码>之后，你需要添加冒号（：）：如果 S和<代码> ELIF  S，即：“BME，你也可能想考虑简化<代码> BMI>＝16，BMI＝BMI。你忘了问一个问题。我建议用<代码>浮动（高度）替换<代码>浮动（高度）*浮动（高度）< /代码>。**2
。谢谢！我能看到并理解所做的改变。
