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 os
    import sys
    import 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()
