dict
一、元素分類
有如下值集合 [11,22,33,44,55,66,77,88,99,90...]，將所有大于 66 的值保存至字典的第一個key中，將小于 66 的值保存至第二個key的值中。 即： {'k1': 大于66的所有值, 'k2': 小于66的所有值}
二、查找
查找列表中元素，移除每個元素的空格，并查找以 a或A開頭 并且以 c 結尾的所有元素。
li = ["alec", " aric", "Alex", "Tony", "rain"]
tu = ("alec", " aric", "Alex", "Tony", "rain")
dic = {'k1': "alex", 'k2': ' aric',? "k3": "Alex", "k4": "Tony"}
?
三、輸出商品列表，用戶輸入序號，顯示用戶選中的商品
商品 li = ["手機", "電腦", '鼠標墊', '游艇']
四、購物車
功能要求：
?要求用戶輸入總資產，例如：2000
?顯示商品列表，讓用戶根據序號選擇商品，加入購物車
?購買，如果商品總額大于總資產，提示賬戶余額不足，否則，購買成功。
?附加：可充值、某商品移除購物車
