下面小编就为大家分享一篇python读文件保存到字典,修改字典并写入新文件的实例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

实例如下所示：

				?

									tcode={}

									transcode={}

									def GetTcode():

									#从文本中获取英文对应的故障码，并保存在tcode字典(故障码文本样例：oxff,0xff,0x00,0x01,    "Fuel Volume Regulator Control Circuit High")

									    with open('text_en.txt','r+')as fileone:

									        for line in fileone.readlines():

									            if not line:

									                continue

									            line=line.strip()

									            titems=line.split('\t')

									            strkey=titems[0].lower()

									            strtemp=titems[1]

									            tcode[strkey]=strtemp

									def GetTransCode():

									#从文本中获取中文对应的故障码，并保存在tcode字典(故障码文本样例：oxff,0xff,0x00,0x01,    "燃油调节器控制电路过高")

									    with open('text_cn.txt','r+') as fileone:

									        for line in fileone.readlines():

									            if not line:

									                continue

									            line=line.strip()

									            transcode[line.split('\t')[0].lower()]=line.split('\t')[1]

									def ReplaTransCode():

									#将已经翻译的中文故障码在英文文本中用ID查找出来并替换，对新的tcode字典key进行排序，并写入新的文本中

									    for findkey in transcode.keys():

									        if tcode.get(findkey,-1)!= -1:

									            tcode[findkey]=transcode[findkey]

									    templine=[]

									    lkeys=tcode.keys()

									    lkeys.sort()

									    for key in lkeys:

									        value=tcode.get(key)

									        key=key.upper().replace("0X","0x")

									        templine.append("%s\t%s\n"%(key,value))

									    with open('text_trans.txt','w+') as filetwo:

									        filetwo.writelines(templine)

									if __name__ == '__main__':

									    GetTcode()

									    GetTransCode()

									    ReplaTransCode()
