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()
