03运行超市抹零结账行为：

money_all = 56.75 + 72.91 + 88.50 + 26.37 + 68.51
money_all_str = str(money_all)
print(" 商品总金额为：" + money_all_str)
money_real = int(money_all)
money_real_str = str(money_real)
print("实收金额为：" + money_real_str)
print("学号后四位：3126")

 

 04计算学生成绩的分差和平均分：

python = 95
english = 92
c = 89
sub = python - c
avg = (python + english + c)/3
print("Pyhon课程和C语言课程的分数之差: " + str(sub) + "分\n")
print("3门课的平均分：" + str(avg) + "分")
print("学号后四位：3126")

 

 05比较运算符比较大小关系：

python = 95
english = 92
c = 89
print("python = " + str(python) + "english = " +str(english) + "c = " +str(c) + "\n")
print("python < english的结果:" + str(python < english))
print("python > english的结果:" + str(python > english))
print("python == english的结果:" + str(python == english))
print("python != english的结果:" + str(python != english))
print("python <= english的结果:" + str(python <= english))
print("python >= c的结果:" + str(python >= c))
print("学号后四位：3126")

 

 

06手机店打折活动：

print("\n手机店正在打折，活动进行中……")
strweek = input("请输入中文星期(如星期一):")
intTime = int(input("请输入时间中的小时（范围：0~23）:"))
if(strweek == "星期二" and (intTime >= 10 and intTime <= 11)) or (strweek == "星期五" and (intTime >= 14 and intTime <= 15)):
print("恭喜您，获得了折扣活动参与资格，快快选购吧！")
