1到100的加法

i = 1 
result = 0
while i <= 100:result += ii += 1
print(result)

搬家具

class Furniture():def __init__(self,name,area):self.name = nameself.area = areaclass Home():def __init__(self,address,area):self.address = addressself.area = areaself.free_area = areaself.furniture = []def __str__(self):return f"房子地理位置{self.address},房屋面积是{self.area},剩余面积{self.free_area},家具有{self.furniture}"def add_furniture(self,item):if self.free_area >= item.area:self.furniture.append(item.name)self.free_area -= item.areaelse:print('无法容纳更多的家具')F1 = Furniture('沙发',10)
F2 = Furniture('双人床',30)addHome = Home('上海',2000)addHome.add_furniture(F1)print(addHome)
addHome.add_furniture(F2)print(addHome)

办公室人员分配

offices = [[],[],[]]
teachers =["李老师","王老师","牛老师","黄老师","庄老师","陈老师","毕老师","何老师"]import randomfor name in teachers: # 先挑选老师num = random.randint(0,2)offices[num].append(name) # 随机选取教室，将老师安排进去i = 1 
for office in offices:print(f'第{i}办公室，人数为{len(office)}') # 读出进入到教室的老师for name in office:print(f'{name} ',end='')print()print()i += 1

猜拳游戏

import randomwhile True:player = int(float(input("请输入数字-1.剪刀、2.石头、3.布：")))computer = random.randint(1,3)if (player == 1) and (computer == 2) or (player == 2) and (computer == 1) or (player == 3) and (computer == 1):print("玩家获胜")elif player == computer:print("平局")else:print("电脑获胜")

乘公交车

money = 1 # 用1和0表示有或没有
seat = 1if money == 1:print('请上车')if seat == 1:print('请坐下')else:print('无座')
else:print('请步行')

吃苹果

i = 0
while i < 5:if i == 3:print('我已经吃饱了')break # 条件生效后，直接中断这次的循 （中断）i += 1
print(f'吃完{i}个苹果，饱了')j = 1
while j < 5:if j == 3:print(f'第{j}个有虫子')j += 1continue # 迭代 跳出这个循环print(f'一共吃了{j}个苹果')j += 1
print('吃完这些苹果')

九九乘法表

i = 1
while i<=9:j = 1while j <= i:print(f"  {i}*{j}={i*j}",end="")j += 1print()i += 1

烤地瓜

class SweetPotato():def __init__(self):self.cook_time = 0self.cook_state = '生的'self.condiments = []def cook(self,time):self.cook_time += timeif 0<= self.cook_time <3:self.cook_state = '生的'elif 3<= self.cook_time <6:self.cook_state = '半生'elif 6<= self.cook_time <8:self.cook_state = '全熟'elif 8<= self.cook_time :self.cook_state = '烤糊'def add_condiments(self,condiment):self.condiments.append(condiment)def __str__(self):return f"这个地瓜烤了{self.cook_time}分钟，状态是{self.cook_state},调料{self.condiments}"if __name__ == "__main__":CookingDiGua = SweetPotato()print(CookingDiGua)CookingDiGua.cook(1)CookingDiGua.add_condiments("盐巴")print(CookingDiGua)CookingDiGua.cook(2)CookingDiGua.add_condiments("酱油")print(CookingDiGua)CookingDiGua.cook(3)print(CookingDiGua)

奇偶100内相加

i = 1
result = 0
while i <= 100:if i % 2 == 0:result += ii += 1
print(result)j = 0 
result = 0
while j <= 100:result += jj += 2
print(result)

三角形

j = 0
while j < 5:i = 0while i < j:print('*',end="")i += 1print()j += 1

正方形

j = 0
while j <4:i = 0while i <7:print('*',end="")i += 1print()j += 1

文件备份

old_file = input('请输入您需要的备份文件名：')index = old_file.rfind('.')new_file = old_file[:index] + '[备份]' + old_file[index:]print(new_file)old_f = open(old_file,'rb')
new_f = open(new_file,'wb')while True:con = old_f.read(1024)if len(con) == 0:breaknew_f.write(con)old_f.close()
new_f.close()   

学员管理系统（函数版）
