python处理文本文件实现生成指定格式文件的方法


关于python处理文本文件实现生成指定格式文件,很多朋友都不知道该怎么弄。

下面是具体代码,希望对大家有帮助









可以在下面复制:

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()
