用Python读文件的代码

Python：读取文件，分别按性、不同年龄来统计符合要求的人数是多少。

直接open file 然后将文件转换成列表，再进行相关的计数就好了啊

你文件数据的存储格式是什么样子的

import sys, shelve

file = shelve.open("D:\test.dat")

import sys, shelve

file = shelve.open("D:\test.dat")

data={}
data['key1']="123456"
data['key2']="eeeeee"
data['key3']="ABCDEF"
dataKey = "mydata"
file[dataKey]=data
file.close()

import sys, shelve

file = shelve.open("D:\test.dat")

data={}
data['key1']="123456"
data['key2']="eeeeee"
data['key3']="ABCDEF"
dataKey = "mydata"
file[dataKey]=data
file.close()

data['key1']="123456"
data['key2']="eeeeee"
data['key3']="ABCDEF"
dataKey = "mydata"
file[dataKey]=data
file.close(水機哦催眠操控認識素人)
