带有关键词的行 txt文本处理

原本的代码（只筛选出来自己要的）（【python】文本处理：删除包含关键词的行、删除指定列、删除指定字符、替换关键字……_bandaoyu的博客-CSDN博客_python 删除csv还有特定词语的某列）

#!/bin/env python

import shutil, sys, os

noneed = ["null"]

need = ['{']

def isInArray(array, line):

    for item in array:

        if item in line:

            return True

    return False

fname = r'D:\download.json'

fresult = r'D:\download2.json'

# open(fname, 'r', encoding='gb2312')

with open(fname, 'r', encoding='UTF-8') as f:

    with open(fresult, 'w', encoding='UTF-8') as g:

        for line in f.readlines():

            if isInArray(need, line):  # 含need里面字符的行 都要

                g.write(line)

                continue

            if not isInArray(noneed, line):  # 不含noneed里面字符的行 都要

                g.write(line)

自己改的

#!/bin/env python

import shutil, sys, os

#noneed = [,"","","","","","","","","","",""]

need = ['updated','content']

def isInArray(array, line):

    for item in array:

        if item in line:

            return True

    return False

fname = r'D:\Desktop\json.txt'

fresult = r'D:\Desktop\json2.txt'

# open(fname, 'r', encoding='gb2312')

with open(fname, 'r', encoding='UTF-8') as f:

    with open(fresult, 'w', encoding='UTF-8') as g:

        for line in f.readlines():

            if isInArray(need, line):  # 含need里面字符的行 都要

                g.write(line)

                g.write("\n")

            else:

                continue # 含有不需要便直接跳过

            # if not isInArray(noneed, line):  # 不含noneed里面字符的行 都要

            #     g.write(line)
