Python 스크립팅 기초 - BMI 계산기

요약
In today's post I will walk you step by step on how to write a basic python script to calculate your body mass index(B.M.I). We will ask the user for some input, and based on it, calculate their B.M.I and return also tell the user, which category their B.M.I falls under. Body mass index is defined by the formula as below:
B.M.I = [your weight in (Kg) / (your height in (m))^2]
Kg - Kilogram
m - metre
There are several defined B.M.I categories, such as:
Underweight = B.M.I below < 18.5.
Normal weight = B.M.I between 18.5-24.9.
Overweight = B.M.I between 25-29.9.
Obesity = B.M.I 30 or above 30.

사용자로부터 데이터 가져오기
>>> user_name = input("Enter your name: ")
Enter your name: Soumyajyoti Biswas
>>> print(user_name)
Soumyajyoti Biswas
>>>
user_name = input("Enter your name: ")
user_weight = float(input("Enter your weight in Kg(s): "))
user_height = float(input("Enter your height in cm(s): "))
B.M.I 계산하기
- Lets take the data that the user provided and put it through our B.M.I formula. Note that the user is providing their height in cm(s). So we will convert that to metre first. To convert cm to m, you divide it by 100.
>>> user_name = input("Enter your name: ")
Enter your name: Soumyajyoti Biswas
>>> user_weight = float(input("Enter your weight in Kg(s): "))
Enter your weight in Kg(s): 70
>>> user_height = float(input("Enter your height in cm(s): "))
Enter your height in cm(s): 165
>>> bmi = round(user_weight/((user_height/100) ** 2),1)
>>> print(bmi)
25.7
# Error displayed if you try to cast a string to a float. [Ref1]
>>> x = input()
12345
>>> type(x)
<class 'str'>
>>> x + x
'1234512345'
>>> type(x + x)
<class 'str'>
>>> x / 10

>>> if bmi < 18.5:
... result = "Underweight"
... elif bmi >= 18.5 and bmi <= 24.9:
... result = "Normal"
... elif bmi >= 25 and bmi <= 29.9:
... result = "Overweight"
... else:
... result = "Very overweight"
...
>>> print(result)
Overweight
함께 모아서
- Let's put all the code together to build a script
user_name = input("Enter your name: ")
user_weight = float(input("Enter your weight in Kg(s): "))
user_height = float(input("Enter your height in cm(s): "))
bmi = round(user_weight/((user_height/100) ** 2),1)
if bmi < 18.5:
result = "Underweight"
elif bmi >= 18.5 and bmi <= 24.9:
result = "Normal"
elif bmi >= 25 and bmi <= 29.9:
result = "Overweight"
else:
result = "Very overweight"
print(f"Hello {user_name}. Your BMI is {bmi}. Your body mass index is {result}.")
