python将一个文件的内容写入另一个文件_Python3中如何将文件中两个关键词中的信息写入

我写的代码：但是从第8行开始就有语法错误了

#coding=utf-8

import re

import os

import shutil

str1='原因：'

str2='可能的后果：'

import codecs

def writetxt('H:/graduation design/data-txt/oil-gas separator/low-flow1.txt', content, code):

with codecs.open('H:/graduation design/data-txt/oil-gas separator/low-flow1.txt', 'a', encoding='utf-8')as f:

f.write(content)

return path+' is ok!'

with open('H:/graduation design/data-txt/oil-gas separator/low-flow.txt') as fp1:

l1 = fp1.readlines()

for linea in fp1.readlines():

linea=linea.replace("\n","").split("\t")

d = dict([linea.split('str1') for s in linea.split('str2')])
