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()
