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')

Answer 1

您的代码有多个问题：

将它们列在这里：

requestNumber不是python中的方法。导入具有此方法的库。或使用默认的input方法。

weight = requestNumber("Enter weight (kg)")

instead

weight = input("Enter weight (kg)")

在结束时你应该有一个'：'

例如：if bmi <= 15:

if bmi=<15也是错误的。它应该是if bmi <= 15:

从您的问题中删除输入代码部分。

elif bmi >=35 and bmi<=40 enter code here
代码中的最后一行但是1行的错误。它应该是＆gt; =

elif bmi <=40

print ('Your weight status is Very Severely Obese')

工作代码：

def calc_BMI():
    weight = input("Enter weight (kg)")
    height = input("Enter Height (meters)")
    bmi = (int(weight)/(float(height)**2))
    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')

输出：

calc_BMI()

Enter weight (kg)78
Enter Height (meters)1.8
Your BMI in 24.074074
Your weight staus is Normal

有用的说明：

尝试遵循编码惯例，例如pep-8 [Link]
正确缩进代码。看看我如何在'＆gt; ='之前和之后添加空格。这也是pep-89惯例的一部分。

例如：如果重量> = 40：

您的代码中存在多个错误，我已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
