47：字典_复杂表格数据存储_列表和字典综合嵌套

###表格数据使用字典和列表存储，并实现访问

源代码（mypy_09.py）：

r1 = {"name":"高小一","age":18,"salary":30000,"city":"北京"}
r2 = {"name":"高小二","age":19,"salary":20000,"city":"上海"}
r3 = {"name":"高小五","age":20,"salary":10000,"city":"深圳"}

tb = [r1,r2,r3]

#获得第二行的人的薪资
print(tb[1].get("salary"))

#打印表中所有的的薪资
for i in range(len(tb)): # i -->0,1,2
print(tb[i].get("salary"))

#打印表的所有数据
for i in range(len(tb)):
print(tb[i].get("name"),tb[i].get("age"),tb[i].get("salary"),tb[i].get("city"))
