计算体重指数

Question

我正在写一个程序，它将提示用户输入6个想要计算其体重指数的个人的名字，然后提示每个人的身高和体重。然而，我似乎不知道如何从我创建的列表中选择一个人。它会一直选择所有输入的名字。有人能建议我如何一次只选择一个人吗？谢谢

print ("This program will help calculate the body mass index of 6 people")
users = str(input("Please enter the names of the 6 users who want to calculate thier BMI: "))
individuals = list()
individuals.append(users)
userA = individuals[0:1]
for userA in individuals:
    height = int(input("In inches, how tall are you? "))
    weight = int(input("In pounds, how much do you weight? "))
    BMI = print(userA, "Your BMI is: ", weight * 703/height**2)

Answer 1

在输入上循环六次，所有的列表都将工作，例如：

print ("This program will help calculate the body mass index of 6 people")
individuals = list()
for i in range(6):
    user = str(input("Please enter the names of the 6 users who want to calculate their BMI: "))
    individuals.append(user)
for user in individuals:
    print("Calculating for", user)
    height = int(input(user + ", in inches, how tall are you? "))
    weight = int(input(user + ", in pounds, how much do you weight? "))
    BMI = print(user  + ", your BMI is: ", weight * 703/height**2)

编辑

以下是在列表中存储BMI的版本

print ("This program will help calculate the body mass index of 6 people")
individuals = list()
for i in range(6):
    user = str(input("Please enter the names of the 6 users who want to calculate their BMI: "))
    individuals.append(user)
BMIs = []
for user in individuals:
    print("Calculating for", user)
    height = int(input(user + ", in inches, how tall are you? "))
    weight = int(input(user + ", in pounds, how much do you weight? "))
    BMIs.append(user  + ", your BMI is: " + str(weight * 703/height**2))

for BMI in BMIs:
    print(BMI)

Answer 2

试试这个吧

print ("This program will help calculate the body mass index of 6 people")
users = str(input("Please enter the names of the 6 users who want to calculate thier BMI (comma separated): "))

users = users.split(',')
print(users)
userA = users[0]
userA

#This program will help calculate the body mass index of 6 people
#Please enter the names of the 6 users who want to calculate thier BMI (comma separated):  a,b,c,d
#['a', 'b', 'c', 'd']
#'a'

Answer 3

这样行得通吗？

Testrun：

python BMI.py

Enter height in meters: 1.75
Enter weight in kg: 64
Your BMI is: 20.897959183673468 and you are: Healthy

Python代码：

# getting input from the user and assigning it to user

height = float(input("Enter height in meters: "))
weight = float(input("Enter weight in kg: "))

# the formula for calculating bmi

bmi = weight/(height**2) 
# ** is the power of operator i.e height*height in this case

print("Your BMI is: {0} and you are: ".format(bmi), end='')

#conditions
if ( bmi < 16):
   print("severely underweight")

elif ( bmi >= 16 and bmi < 18.5):
   print("underweight")

elif ( bmi >= 18.5 and bmi < 25):
   print("Healthy")

elif ( bmi >= 25 and bmi < 30):
   print("overweight")

elif ( bmi >=30):
   print("severely overweight")
