python读写文件

1、从文件按行读出，并转为dict格式。注意：下面例子中文件中只有一行。

读

import io
import json
def FunReadFile():
    localDict={}
    try:
        with io.open('test.txt', 'r',encoding='utf-8') as f:
            for line in f.readlines():
                print("localDict",line.strip())
                strs = line.strip()
                strs = strs.replace('"','')
                strs = strs.replace("'",'"')
                print("strs",strs)
                localDict = json.loads(strs)
    except IOError:
        print "FunReadFile failed!"
    return localDict

写

def FunWriteFile(localDic):
    try:
        with open('test.txt', 'w+') as f:
            print("localDic", localDic)
            f.write(str(localDic))
    except IOError:
        print "FunWriteFile failed"

解决：1、读的时候，行首和行尾会有引号，用replace函数去掉；再把内容中单引号转为双引号，否则转json会报错；

ValueError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
