一、购物车1.0
需求:
(1)打印产品列表里的产品
(2)写一个循环不断问用户想买什么，用户选择一个商品编号，把对应的商品编号添加到购物车，打印购物车里的商品列表
from curses.ascii import isdigit
production_list=[
("Iphone",6700),
("Macbook_pro",13000),
("Bike",800),
("sceient_book",60),
("Coffee",20),
("Airpods",2400),
("imac_pro",24000),
]
# 高亮输出字符串
def output_highlight(s):
print('\033[1;31;40m%s\033[0m' % s)
salary = input("please input your salary:")
shopping_list = []
if salary.isdigit():
salary = int(salary)
while True:
for index,item in enumerate(production_list):
print(index,item)
user_choice = input("Please enter the number you want to purchase：")
if user_choice.isdigit():
user_choice = int(user_choice)
if user_choice < len(production_list) and user_choice >= 0:
p_item = production_list[user_choice]
if p_item[1] < salary:
shopping_list.append(p_item)
salary -= p_item[1]
output_highlight ("%s has add your shopping car,The current balance is [%s]" %(p_item,salary)) #增加高亮显示
else:
print("The balance is insufficient. Your current balanceis [%s]" %salary)
print("---------A list of items already purchased----------------")
for p in shopping_list:
print(p)
output_highlight("If the balance is insufficient, the program exits")
exit()
else:
output_highlight("The shop code [%s] doesn't exist!" % user_choice)
elif user_choice == 'q':
print("---------A list of items already purchased----------------")
for p in shopping_list:
output_highlight(p)
output_highlight("The program is about to exit")
exit()
else:
output_highlight("input parameters invaild,the program will exit")
exit()
else:
output_highlight("invaild parameters,The program is about to exit!")
二.简单三级菜单
menu={'中国':{'广东':{'广州':{'天河区','海珠区','南沙区'},'深圳':{'南山区','龙岗区','福田区'},'惠州':{'惠阳区','淡水区','惠城区'}},
'北京':{'昌平':{'好','很好','非常好'},'海淀':{'好','很好','非常好'},'朝阳':{'好','很好','非常好'}},
'山西':{'太原':{'好','很好','非常好'},'大同':{'好','很好','非常好'},'运程':{'好','很好','非常好'}}},
'美国':{'纽约州':{'纽约市':{'好','很好','非常好'},'罗彻斯特':{'好','很好','非常好'},'水牛城':{'好','很好','非常好'}},
'加利福利亚州':{'洛杉矶':{'好','很好','非常好'},'好莱坞':{'好','很好','非常好'},'阿罕布拉':{'好','很好','非常好'}},
'宾夕法尼亚州':{'费城':{'好','很好','非常好'},'伯利恒':{'好','很好','非常好'},'华盛顿':{'好','很好','非常好'}}},
'澳大利亚':{'维多利亚州':{'墨尔本':{'好','很好','非常好'},'吉朗':{'好','很好','非常好'},'巴里迪':{'好','很好','非常好'}},
'西澳大利亚州':{'马扎尔':{'好','很好','非常好'},'柏斯':{'好','很好','非常好'},'费里曼图':{'好','很好','非常好'}},
'南澳大利亚州':{'阿德莱德':{'好','很好','非常好'},'内陆':{'好','很好','非常好'},'巴罗莎':{'好','很好','非常好'}}}}
is_status = False
while not is_status:
for options in menu:
print (options)
user_choice = input("Please enter your choice>>>")
if user_choice in menu:
while not is_status:
for options2 in menu[user_choice]:
print("\t",options2)
user_choice2 = input("Please enter your choice2>>>")
if user_choice2 in menu[user_choice]:
while not is_status:
for options3 in menu[user_choice][user_choice2]:
print("\t\t",options3)
user_choice3 = input("Please enter your choice3>>>")
if user_choice3 in menu[user_choice][user_choice2]:
while not is_status:
for options4 in menu[user_choice][user_choice2][user_choice3]:
print("\t\t",options4)
user_choice4 = input("return>>>：")
if user_choice4 == "b":
break
elif user_choice4 == "q":
is_status = True
if user_choice3 == "b":
break
elif user_choice3 == "q":
is_status = True
if user_choice2 == "b":
break
elif user_choice2 == "q":
is_status = True
三.python 生成器练习脚本
import time
def comsumer(name):
print ("{}准备消费饺子了".format(name))
while True:
jiaozi = yield
print ("饺子{0},被消费者{1}吃掉了".format(jiaozi,name))
#return name
def produce(name):
C = comsumer('ben')
C1 = comsumer('fio')
C.__next__()
C1.__next__()
for i in range(10):
time.sleep(1)
print("饺子被做好了，现在分成两份")
C.send(i)
C1.send(i)
produce("jack")
四.python 自定义本地时间函数
import time
def log_timer():
loger_time = time.localtime()
print(loger_time)
local_time=time.strftime("%Y-%m-%d %H:%M:%S",loger_time)
print(local_time)
log_timer()
五.python随机生成6位验证码
def check_code(n=6):
code = ''
for i in range(n):
r = random.randint(0,5)
if r == 1 or r == 4:
num = random.randint(0,9)
code = code + str(num)
else:
alpha = chr(random.randrange(65,90))
code = code + alpha
print(code)
check_code()
