pythonBMI循环

Sure! Here's an example of a Python program that calculates BMI (Body Mass Index) using a loop:

# BMI Calculation using a loop

# Number of people
num_people = int(input("Enter the number of people: "))

# Loop through each person
for i in range(num_people):
    print(f"\nPerson {i+1}")
    weight = float(input("Enter weight in kilograms: "))
    height = float(input("Enter height in meters: "))
    
    # Calculate BMI
    bmi = weight / (height ** 2)
    print(f"BMI: {bmi:.2f}")
    
    # Interpret BMI
    if bmi < 18.5:
        print("Underweight")
    elif bmi < 25:
        print("Normal weight")
    elif bmi < 30:
        print("Overweight")
    else:
        print("Obese")

In this program, we first ask the user for the number of people they want to calculate BMI for. Then, using a loop, we prompt for weight and height inputs for each person. The BMI is calculated using the formula weight / (height^2). Finally, we interpret the BMI based on standard ranges and output the result.
