Question

def male_resting_metabolic_rate(weight,height,age):

  '''Takes in the weight, height, and age of a male individual
  and returns the resting metabolic rate

Example answers: 
    male_resting_metabolic_rate(80,180,48) = 1751'''

   male_resting_metabolic_rate = int((88.4+13.4*weight)+(4.8*height)-(5.68* age))

 if __name__ == "__main__":
print("This program will calculate the resting metabolic rate of an individual")

  #Gather the inputs for the functions 

 weight = input("What is your weight in kilograms?")
 height = input("What is your height in centimeters?")
 age = int(input("What is your age?" + "(between 1-110):"))

 print("Your resting metabolic rate is",male_resting_metabolic_rate(input,input,input))

为什么它说我在第10行和第24行有错误？这是一个全新的问题，如果答案很明显的话，我很抱歉。在

Answer 1

发现了至少两个错误：您需要在python中使用“return”返回值。此外，您还需要按名称传递参数，而不是“input”

试试这个：

def male_resting_metabolic_rate(weight,height,age):

  '''Takes in the weight, height, and age of a male individual
  and returns the resting metabolic rate

  Example answers: 
    male_resting_metabolic_rate(80,180,48) = 1751'''

    return int((88.4+13.4*weight)+(4.8*height)-(5.68* age))

 if __name__ == "__main__":
   print("This program will calculate the resting metabolic rate of an individual")

   #Gather the inputs for the functions 

   weight = float(input("What is your weight in kilograms?"))
   height = float(input("What is your height in centimeters?"))
   age = int(input("What is your age?" + "(between 1-110):"))

   print("Your resting metabolic rate is",male_resting_metabolic_rate(weight, height, age ))
