python读文件保存到字典,修改字典并写入新文件的实例
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()
