特将课后作业记录如下

一、实现体脂率公式计算

gender = input('请输入您的性别（男性填写1或女性填写2）:')
print(gender)

waistline = input('请输入您的腰围（cm）:')
print(waistline)

weight = input('请输入您的体重（kg）：')
print(weight)
gender = int(gender)
waistline = float(waistline)
weight = float (waistline)

a = waistline*0.74
if gender == 1:
    b = weight*0.082+44.47
else:
    b = weight*0.082+34.89
lipweight = a - b
BMI = lipweight/weight
print('您的体脂率为：','%.2f%%'%(BMI*100))

二、采用for语句实现九九乘法表

for row in range(1,10):
    for column in range(1,10):
        if column <= row:
            print('%s*%s=%s'%(column,row,column*row),end='  ')
        else:
            print('')
            break

三、计算水仙花数

for n in range(100,1000):
    a = n//100
    b = (n-a*100)//10
    c = n-a*100-b*10
    if (a**3+b**3+c**3) == n:
        print(n,'是水仙花数')

老师还给出了另一种解法参考：

for value in range(100,1000):
    x = int(str(value)[0])
    y = int(str(value)[1])
    z = int(str(value)[2])
    if value == (x**3 +y **3 +z **3):
        print(u"%s是水仙花数"%value)
