实战2

实战2：

1。字符串与字典的转换
str1='学无止尽'
str_dict=dict(enumerate(str1))
print(str_dict)
print(type(str_dict))

dict_str=str(str_dict)
print(dict_str)
print(type(dict_str))
2。输出c
lists=['language',['go','python',['java','net',['c']]]]
print(lists[-1][-1][-1][-1])
3。输出分数的最高，最小，平均 总和
dict1={'name':'wuya',"score":[
  {"score":90},
  {'score':88},
  {'score':60}]}
list1=[]
for item in dict1['score']:
   list1.append(item['score'])
print('最大',max(list1))
print('最小',min(list1))
print('平均',sum(list1)/len(list1))
print('和',sum(list1))

4。输出唐山
datas=["go",{"name":'lisi',"age":18,'address':["xian",'唐山']}]
print(datas[-1]['address'][-1])
5。按照key和value进行排序
dict2={'name':'wuya',"sex":"boy","job":"testDev","salary":109.09}
date=dict(sorted(dict2.items(),key=lambda s:s[0]))
print(date)
6.获取所有的城市
