本文所述實例為Python處理文本文件并生成指定格式文件的方法，具體實現功能代碼如下所示：

import osimport sysimport string#以指定模式打開指定文件，獲取文件句柄def getFileIns(filePath,model):  print("打開文件")  print(filePath)  print(model)  return open(filePath,model)#獲取需要處理的文件def getProcFile(path):  return os.listdir(path)#判斷是否滿足某個條件，如果滿足則執行def isTrue(outFileIns,s):  findStr1 = "LINE_COUNT_UPDATE   INTEGER := 0;"  writeStr1 = "LINE_COUNT_ERROR    INTEGER := 0;    --錯誤數據XX條"  findStr2 = "DBMS_OUTPUT.PUT_LINE('處理完畢"  writeStr2 = "DBMS_OUTPUT.PUT_LINE('錯誤數據['||LINE_COUNT_ERROR||']條.');"  findStr3 = "DBMS_OUTPUT.PUT_LINE('插入數據['||CUR_RESULT.INT_ID||']時發生異常...');"  writeStr3 = "LINE_COUNT_ERROR := LINE_COUNT_ERROR+1;"  findStr4 = "DBMS_OUTPUT.PUT_LINE('更新數據['||CUR_RESULT.INT_ID||']時發生異常...');"    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"))        #讀取并處理文本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+"http://"+tmpFile    outFilePath = path+"http://BAK_"+tmpFile    inFileIns = getFileIns(inFilePath,inFileMod)    outFileIns = getFileIns(outFilePath,outFileMod)    getAndProc(inFileIns,outFileIns)    inFileIns.close()    outFileIns.close()
