1. Given a grade, determine the grade of the grade
score = int(input("输入你的成绩"))
if score == 100:
print("满分")
elif 90 <= score < 100:
print("优秀")
elif 80 <= score < 90:
print("良好")
elif 70 <= score < 80:
print("还可以，多多努力")
elif 60 <= score < 70:
print("合格")
elif 0 <= score < 60:
print("不合格")
elif score == 0:
print("鸡蛋")
2. Determine whether a number is odd or even
num = int(input("请输入一个数:"))
if (num % 2) == 0:
print("{0}是偶数".format(num))
else:
print("{0}是奇数".format(num))
3. Determine whether a year is a leap year
year = int(input("输入一个年份"))
if (year % 4 != 0 and year % 100 != 100) and year % 400 == 0:
print("闰年")
else:
print('不是闰年')
4. Determine a person’s BMI
tall = float(input("输入身高"))
weight = int(input("输入体重"))
BMI = weight / (tall * tall)
if 35 <= BMI:
print("重度肥胖")
elif 30 <= BMI < 35:
print("中度肥胖")
elif 27 <= BMI < 30:
print("轻度肥胖")
elif 24 <= BMI < 27:
print("过重")
elif 18.5 <= BMI < 24:
print("正常")
else:
print("过轻")
5. Use Hailun Company to find the perimeter and area of a triangle
a = float(input('输入三角形第一边长： '))
b = float(input('输入三角形第二边长： '))
c = float(input('输入三角形第三边长： '))
while a+b<c or a+c<b or b+c<a:
print('输入的边构不成三角形，请重新输入！')
a =float(input ('输入三角形第一边长：'))
b =float(input ('输入三角形第二边长：'))
c =float(input ('输入三角形第三边长：'))
# 计算半周长
s = (a + b + c) / 2
# 计算面积
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('三角形面积为 %0.2f' %area)
6. Operation symbols of two numbers
a = float(input("输入第一个数"))
b = float(input("输入第二个数"))
c = a + b
print("两数之和为%0.2f" % c)
d = a - b
print("两数之差为%0.2f" % d)
e = a / b
print("两数相除%0.2f" % e)
f = a % b
print("两数取模 %0.2f" % f)
g = a // b
print("两数相除取整数 % f" % g)
h = a ** b
print("两数乘方 % f" % h)
7. Determine whether a number is an exponent of 2
Index of 2
0000 0010 0000 0001
0000 0100 0000 0011
0000 1000 0000 0111
0001 0000 0000 1111
num = int(input("请输入一个数字；"))
if (num - 1) == 0:
print("这个数字是2的指数:%s" % num)
else:
print("这个不是2的指数")
8. Calculate the number of weeks in a month based on the number of days
days = int(input("请输入一个数："))
week = days//7
if week == 0:
print("这是第一周")
elif week == 1:
print("这是第二周")
elif week == 2:
print("这是第三周")
elif week == 3:
print("这是第四周")
elif week == 4:
print("这是第五周")
elif week == 5:
print("这是第六周")
elif week == 6:
print("这是第七周")
elif week == 7:
print("这是第八周")
else:
print("这是第**周")
9. Exam score rewards
grade = int(input("请输入成绩："))
if 100 < grade or grade < 0:
print("成绩输入错误，请重新输入")
elif grade == 100:
print('爸爸要给你买车')
elif grade >= 90:
print('你妈妈要给你买MP4')
elif 90 > grade >= 60:
print('妈妈要给你买本参考书')
elif 60 > grade >= 0:
print('什么都不买')
