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 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()
