python处理文本文件实现生成指定格式文件的方法

本文所述实例为python/' target='_blank'>python处理文本文件并生成指定格式文件的方法，具体实现功能代码如下所示：

import osimport sysimport string#以指定模式打开指定文件，获取文件句柄def getFileIns(filePath,model):  print("打开文件")  print(filePath)  print(model)  return open(filePath,model)#获取需要处理的文件def getProcFile(path):  return os.listdir(path)#判断是否满足某个条件，如果满足则执行def isTrue(outFileIns,s):  findStr1 = "LINE_COUNT_UPDATE   INTEGER := 0;"  writeStr1 = "LINE_COUNT_ERROR    INTEGER := 0;    --错误数据XX条"  findStr2 = "DBMS_OUTPUT.PUT_LINE('处理完毕"  writeStr2 = "DBMS_OUTPUT.PUT_LINE('错误数据['||LINE_COUNT_ERROR||']条.');"  findStr3 = "DBMS_OUTPUT.PUT_LINE('插入数据['||CUR_RESULT.INT_ID||']时发生异常...');"  writeStr3 = "LINE_COUNT_ERROR := LINE_COUNT_ERROR+1;"  findStr4 = "DBMS_OUTPUT.PUT_LINE('更新数据['||CUR_RESULT.INT_ID||']时发生异常...');"    if s.find(findStr1) != -1:    outFileIns.write(s)    outFileIns.write(writeStr1+"\n")  elif s.find(findStr2) != -1:    outFileIns.write(s)    outFileIns.write(writeStr2+"\n")  elif s.find(findStr3) != -1:    outFileIns.write(s)    outFileIns.write("\t\t\t\t"+writeStr3+"\n")  elif s.find(findStr4) != -1:    outFileIns.write(s)    outFileIns.write("\t\t\t\t\t"+writeStr3+"\n")  elif s.find("CS_OSLGIS") != -1:    outFileIns.write(s.replace("CS_OSLGIS","CQ_RMW"))  elif s.find("AND A.LONGITUDE >") != -1:    outFileIns.write("\t\t\tAND A.LONGITUDE IS NOT NULL\n\t\t\tAND A.LONGITUDE IS NOT NULL\n\t\t\tAND ROWNUM<2\n")  elif s.find(") LOOP") != -1:    outFileIns.write("\t\t) LOOP\n")  else:    outFileIns.write(s.replace("||')',2","||')',3"))        #读取并处理文本def getAndProc(inFileIns,outFileIns):  lines = inFileIns.readlines()  for s in lines:    #print(s)    isTrue(outFileIns,s)if __name__=="__main__":    inFileMod = "r"  outFileMod = "w"  path = "D:\\rmsdata2gis"  for tmpFile in os.listdir(path):    inFilePath = path+"\\"+tmpFile    outFilePath = path+"\\BAK_"+tmpFile    inFileIns = getFileIns(inFilePath,inFileMod)    outFileIns = getFileIns(outFilePath,outFileMod)    getAndProc(inFileIns,outFileIns)    inFileIns.close()    outFileIns.close()
