關於列表,元組,字典的小練習
元素分類
有如下值集合 [11,22,33,44,55,66,77,88,99,90…]，將所有大於 66 的值保存至字典的第一個key中，將小於 66 的值保存至第二個key的值中。
即： {‘k1’: 大於66的所有值, ‘k2’: 小於66的所有值}
def work1():
m_list = [11,22,33,44,55,66,77,88,99,90]
m_dics = {'k1':[],'k2':[]}
for i in m_list:
if i > 66:
m_dics.get('k1').append(i)
elif i < 66:
m_dics.get('k2').append(i)
else:
print("66--->我該去哪")
print(m_dics)- 查找
查找列表中元素，移除每個元素的空格，並查找以 a或A開頭 並且以 c 結尾的所有元素。
li = [“alec”, ” aric”, “Alex”, “Tony”, “rain”]
tu = (“alec”, ” aric”, “Alex”, “Tony”, “rain”)

商品 li = [“手機”, “電腦”, ‘鼠標墊’, ‘遊艇’]

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，如果商品總額大於總資產，提示賬戶餘額不足，否則，購買成功。
附加：可充值、某商品移除購物車
