编写程序，根据身高和体重计算BMI值，同时输出国际和国内BMI指标建议值所确定的指标分类信息。用python实现

在Python中，我们可以编写一个简单的函数来计算BMI（身体质量指数），并根据标准值判断属于正常、偏瘦、偏胖还是肥胖。这里是一个基本的例子：

def calculate_bmi(height_cm, weight_kg):
    # 将身高从厘米转换为米
    height_m = height_cm / 100.0
    # 计算BMI
    bmi = weight_kg / (height_m ** 2)
    
    # 定义国际和中国的BMI分类标准
    international_thresholds = {
        "Underweight": (18.5, 24.9),
        "Normal": (25, 29.9),
        "Overweight": (30, 34.9),
        "Obese": (>=35)
    }
    chinese_thresholds = {
        "过轻": (18.5, 23.9),
        "正常": (24, 27.9),
        "超重": (28, 29.9),
        "肥胖": (>=30)
    }

    # 根据中国和国际的标准检查BMI
    international_status = ""
    if bmi < international_thresholds["Underweight"][0]:
        international_status = "Underweight"
    elif bmi >= international_thresholds["Underweight"][1] and \
         bmi < international_thresholds["Normal"][0]:
        international_status = "Normal"
    elif bmi >= international_thresholds["Normal"][1] and \
         bmi < international_thresholds["Overweight"][0]:
        international_status = "Overweight"
    else:
        international_status = "Obese"

    chinese_status = ""
    if bmi < chinese_thresholds["过轻"][0]:
        chinese_status = "过轻"
    elif bmi >= chinese_thresholds["过轻"][1] and \
         bmi < chinese_thresholds["正常"][0]:
        chinese_status = "正常"
    elif bmi >= chinese_thresholds["正常"][1] and \
         bmi < chinese_thresholds["超重"][0]:
        chinese_status = "超重"
    else:
        chinese_status = "肥胖"

    return bmi, f"International: {international_status}, Chinese: {chinese_status}"

# 测试函数
height = float(input("请输入您的身高（cm）: "))
weight = float(input("请输入您的体重（kg）: "))
bmi, classification = calculate_bmi(height, weight)
print(f"Your BMI is: {bmi:.2f}")
print(f"BMI Classification: {classification}")
