一般字符串，执行一个功能，生成一个新内容，原来内容不变。
list,tuple,dict，执行一个功能，自身进行变化。
求 a 或 A 还有C 结尾的 元素
li = ['Alix',' aric','alix','Tonc','rain']
dic = {'k1':'Alix','k2':' aric','k3':'alix','k4':'Tony','k5':'rain'}
for i in li:
u = i.lstrip()
w = u.find('A',0,1)
q = u.find('a',0,1)
e = u.find('c',2,4)
if w==0 or q==0 or e==3 :
print(u)
w = dic.values()
for z in w:
u = z.lstrip()
w = u.find('A',0,1)
q = u.find('a',0,1)
e = u.find('c',2,4)
if w==0 or q==0 or e==3 :
print(u)
输出商品列表，用户输入序号，显示用户所选中的商品
commodity = ['手机','电脑','鼠标','键盘']
for i in commodity:
w = commodity.index(i)
print(w+1,i)
inp = input('请输入商品')
u = int(inp)
print(commodity[u-1])
小于66放到small里面 大于66放到large里面

small = {}
