减法竖式

for a in range(1, 10):
    for b in range(0, 10):
        for c in range(0, 10):
            for d in range(0, 10):
                if (a * 100 + b * 10 + 4 - c * 10 - d == c) and a != b != c != d:
                    print("我=", a, "爱=", b, "学=", c, "数=", d)

计算天数（简单）

import time
time1 = input('请输入日期(g格式为:年/月/日):')
time_tuple = time.strptime(time1, '%Y/%m/%d')
print(f"今年第{time_tuple[7]}天")

计算天数（老师版）

y = int(input("请输入年份"))
m = int(input("请输入月份"))
d = int(input("请输入日"))
month = [0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30]
if y % 4 == 0 and y % 100 != 0 or y % 400 == 0:
    month[2] = 29
day = sum(month[0:m]) + d
print(day)

猜数字（设定版）

guess = 0
secret = 56
print("---------欢迎参加猜数字游戏，请开始---------")
while guess != secret:
    guess = int(input("请输入你猜的数字："))
    print("你输入的数字是：", guess)
    if guess == secret:
        print("恭喜，猜数成功")
    else:
        if guess < secret:
            print("很遗憾，你猜小了")
        else:
            print("很遗憾，你猜大了")

print("游戏结束")



猜数字（人机版）

print("你总共有三次猜数字的机会")
if int(input("你第一次输入的数字是：")) == 24:
    print("恭喜你猜对了")
elif int(input("你第二次输入的数字是：")) == 24:
    print("恭喜你猜对了")
elif int(input("你第三次输入的数字是：")) == 24:
    print("恭喜你猜对了")
else:
    print("猜错了，正确的数字是24")

斐波那契数列

def tuzi(n):
    if n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    else:
        tutu = [0, 1]
        while len(tutu) < n:
            m = tutu[-1] + tutu[-2]
            tutu.append(m)
    return tutu


print(tuzi(5))

角谷猜想

def a(n):
    A = 0
    while n != 1:
        if n % 2 == 0:
            n = n // 2
        else:
            n = 3 * n + 1
        A += 1
    return A


num = int(input("请输入一个正整数"))
print(f"经过{a(num)}次变为1")
