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：
importos
importsys
importstring
#以指定模式打开指定文件，获取文件句柄
defgetFileIns(filePath,model):
print("打开文件")
print(filePath)
print(model)
returnopen(filePath,model)
#获取需要处理的文件
defgetProcFile(path):
returnos.listdir(path)
#判断是否满足某个条件，如果满足则执行
defisTrue(outFileIns,s):
findStr1="LINE_COUNT_UPDATEINTEGER:=0;"
writeStr1="LINE_COUNT_ERRORINTEGER:=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...');"
ifs.find(findStr1)!=-1:
outFileIns.write(s)
outFileIns.write(writeStr1+"\n")
elifs.find(findStr2)!=-1:
outFileIns.write(s)
outFileIns.write(writeStr2+"\n")
elifs.find(findStr3)!=-1:
outFileIns.write(s)
outFileIns.write("\t\t\t\t"+writeStr3+"\n")
elifs.find(findStr4)!=-1:
outFileIns.write(s)
outFileIns.write("\t\t\t\t\t"+writeStr3+"\n")
elifs.find("CS_OSLGIS")!=-1:
outFileIns.write(s.replace("CS_OSLGIS","CQ_RMW"))
elifs.find("ANDA.LONGITUDE>")!=-1:
outFileIns.write("\t\t\tANDA.LONGITUDEISNOTNULL\n\t\t\tANDA.LONGITUDEISNOTNULL\n\t\t\tANDROWNUM<2\n")
elifs.find(")LOOP")!=-1:
outFileIns.write("\t\t)LOOP\n")
else:
outFileIns.write(s.replace("||')',2","||')',3"))
#读取并处理文本
defgetAndProc(inFileIns,outFileIns):
lines=inFileIns.readlines()
forsinlines:
#print(s)
isTrue(outFileIns,s)
if__name__=="__main__":
inFileMod="r"
outFileMod="w"
path="D:\\rmsdata2gis"
fortmpFileinos.listdir(path):
inFilePath=path+"\\"+tmpFile
outFilePath=path+"\\BAK_"+tmpFile
inFileIns=getFileIns(inFilePath,inFileMod)
outFileIns=getFileIns(outFilePath,outFileMod)
getAndProc(inFileIns,outFileIns)
inFileIns.close()
outFileIns.close()
