I have a bit of an issue when trying to print for this BMI calculator, at the very end it should look like,
"The BMI for (name) is (BMI number), which is (status, basically if they're underweight, overweight etc.)"
In the getStatus() i am trying to take the numeric value from getBMI() and use it in the if statement. (I don't know why this is big and bold lettered)
The problem arises when I try to print, it's prompts me to input my name, age, weight, and height like normal.
This is what it outputs: NameError: name 'getBMI' is not defined
The reason is in the getStatus function, you are calling getBmi but you should be calling self.getBmi()
The getStatus function should look like this:
def getStatus(self):
if self.getBMI() < 18.5:
self.__getStatus = "Underweight"
elif 18.5 < self.getBMI() < 24.9:
self.__getStatus = "Normal"
elif 25.0 < self.getBMI() < 29.9:
self.__getStatus = "Overweight"
elif self.getBMI() > 30:
self.__getStatus = "Obese"
return self.__getStatus
Also, as input automatically returns a string, you can just say
name = input("What is your name? ")
getBMI is not defined as a global function, and so a NameError is thrown when you try to refer to it as just getBMI. The method of this name cannot be referenced nakedly like this in the way that C++ methods can. Instead, an instance must refer to its methods as attributes of self, i.e. as self.getBMI() in this case.

the code is meant to run in the shell and is a simple class and subclass game that the player creates a character and then assigns it a subclass which changes the attributes of the character. this is where my problems started. in the future I want the character to be able to travel and then will encounter monsters attack and receive damage.
id like to hear some advice on what I could do to improve and make the code better smoother and also fix these problems that have occurred. I've only been coding for a while so there is allot of things wrong with this code.
I have a frame for the python code that calculates bmi.
i have done most of the part but I cannot seem to get around the sentinel loop. The goals are:
user enters a patient identification number (an int), patient name (a string), patient height in inches (a positive float), and patient weight in pounds (a positive float) until the user enters a negative number for the patient ID .
I have done the BMI calculation.
For each patient’s information entered, output a well-formatted result listing the patient’s ID, name, calculated BMI (output with 1 digit of precision) and associated category (Underweight, Obese, etc.). The use of f-strings to produce the formatted output is recommended.
After trying and some googling, here is what I have. I would like help with the sentinel loop.
class BodyMassIndex:
def __init__(self, pid, name, weight, height):
self.patient_id = pid
self.name = name
self.weight = weight
self.height = height
#property
def body_mass_index(self):
return round((self.weight * 703) / self.height ** 2, 1)
#property
def score(self):
if self.body_mass_index < 18.5:
return 'Underweight'
elif self.body_mass_index < 25:
return 'Healthy Weight'
elif self.body_mass_index < 30:
return 'Overweight'
else:
return 'Obese'
def print_score(self):
print('Patient id {}: {} has a bmi score of {}. Patient is {}.'.format(self.patient_id, self.name, self.body_mass_index, self.score))
def _get_user_info():
while True:
try:
pid = int(input("Please enter your 5-digit patient id: "))
p_name = input("Please enter patient first name and last name: ")
weight = float(input('Enter weight in pounds: '))
height = float(input('Enter height in inches: '))
if 0 < weight and 0 < height < 107:
return pid, p_name, weight, height
else:
raise ValueError('Invalid height or weight. Let us start over.')
except ValueError:
print('Invalid height or weight input')
continue
def calculate_bmi():
pid, name, weight, height = _get_user_info()
return BodyMassIndex(pid, name, weight, height)
if __name__ == '__main__':
bmi = calculate_bmi()
bmi.print_score()
I was told I would need to delete the print_score function and instead I should have a table of values entered and bmi result when user entered a wrong/negative patient id. It does not need to be 5-digit patient id.
In my role-playing party creator program, I am trying to have the user create a class object, adding the attributes, and storing it into a party-list index. However, by the time the player goes back to the main menu (the main() function that displays the party list), the slot still shows a None value. Here is my code:

genders = ['Male', 'Female', 'Others']

if int(inp) > 0 and int(inp) < 6:
print("Slot {} selected!".format(int(inp)))
return check(party[inp_1])
party = [None, None, None, None, None]
main()
This is how the program runs so far:
[None, None, None, None, None]
Select a slot:
#User inputs 1
Slot 1 selected!
Choose a creature: 1) Dragon 2) Fairy 3) Mermaid 4) Vampire
#User inputs 1
Pick an attribute to change: 1) name 2) height 3) weight 4) gender 5) save
#User inputs 1
Enter a name: *Name*
Pick an attribute to change: 1) name 2) height 3) weight 4) gender 5) save
#User inputs 5
Save? 1) yes 2) no
#User inputs 1
Saving...
Select an option 1) Show Attributes 2) Change Attributes 3) Delete 4) Back
#User inputs 4
However, after you go back to main(), the list still displays as such:
[None, None, None, None, None]
Select a slot:
What doesn't make sense is that the parameters in the functions should have followed a chain rule that will eventually lead to the party slot. I want it so that a slot index will have a class object stored in it rather than None. As far as I know, I might need to use global variables, but I haven't found out much after that. Any ways to fix this?
Edit: So I managed to fix the problem. I just put the check() function in the main(). It goes like this:
def main():
print(party)
inp = input("Select a slot: ")
inp_1 = int(inp) - 1
if int(inp) > 0 and int(inp) < 6:
print("Slot {} selected!".format(int(inp)))
if party[inp_1] == None:
a = input('Choose a creature: 1) Dragon 2) Fairy 3) Mermaid 4) Vampire')
if int(a) == 1:
slot = Dragon()
elif int(a) == 2:
slot = Fairy()
elif int(a) == 3:
slot = Mermaid()
elif int(a) == 4:
slot = Vampire()
party[inp_1] = slot
return changeAttributes(party[inp_1])
else:
return menu(party[inp_1])
There is no sens of "return" at the end of main. What you should want to do I think is editing the party list. Therefor instead of
return check(party[inp_1])
you should try
party[inp_1] = check(party[inp_1])
Make sure the check function returns a creature type, I'm not sure of that.
there is some really weird interaction you really should try to make class and methods for all of that. In your 4th elseif in the menu function, you shouldn't have to call main again.

I don't understand why though, I thought I had it defined.
I think you miss spelled the word "calculate" on
def caluculate_avg(scores):
change to
def calculate_avg(scores):
The function name is spelled incorrectly 'caluculate'.
Your function name is caluculate_avg but you call calculate_avg
So that is just a typo problem and change this line
def caluculate_avg(scores):
To this
def calculate_avg(scores):
Because there is a typo in function name and calling.
You are defining
def caluculate_avg(scores):
but you are using
scores_averaged = calculate_avg(scores)
Change the function definition to
def calculate_avg(scores):
You called your function with a different name, 'calculate_avg' instead of 'caluculate_avg', make sure you have the same function name when calling it

The BMR function works. The tee keeps throwing errors (mostly on cannot call a float) and when it does not I get something like <function a0…>.
def bmr(gender, age, height, weight):
if gender == "f":
bmr = 655 + weight*9.6 + height*1.6 + age*4.7
else:
bmr = 66 + weight*13.8 + height*5 + age*6.8
return bmr
def tee (bmr, amount_of_exersice):
#x = 0
y = bmr(gender, age, height, weight)
if amount_of_exersice == 0:
x = 1.2
elif 1<= amount_of_exersice <= 2:
x = 1.375
elif 3 <= amount_of_exersice <= 5:
x = 1.55
else:
x = 1.725
z = x * y
return z
A couple of problems, you're redefining "bmr" and you're not passing the right arguments to second bmr call. Try, as example:
def tee (gender, age, height, weight, amount_of_exersice):
y = bmr(gender, age, height, weight)
if amount_of_exersice == 0:
x = 1.2
elif 1<= amount_of_exersice <= 2:
x = 1.375
elif 3 <= amount_of_exersice <= 5:
x = 1.55
else:
x = 1.725
z = x * y
return z
or if you want to define bmr before:
def tee (y, amount_of_exersice):
if amount_of_exersice == 0:
x = 1.2
elif 1<= amount_of_exersice <= 2:
x = 1.375
elif 3 <= amount_of_exersice <= 5:
x = 1.55
else:
x = 1.725
z = x * y
return z
y_bmr = bmr(gender, age, height, weight)
tee(y_bmr, amount_of_exersice)
When you do
def tee(bmr, amount_of_exersize):
You're redefining the name bmr to point to whatever variable you're passing in - whereas, if you hadn't done that, it would have referred to the function above. This replacement applies so long as you're within the method, and the only real solution is to rename the parameter so that it doesn't conflict:
def tee(something_else, amount_of_exersize):
y = bmr(gender, age, height, weight)
