Question

我想将文件循环到一个目录中，在这些文件上创建一些东西，然后为每个文件写出结果。但我的文件无法读取，因为python将文件名解释为字符串对象而不是可读文件。有没有办法避免这种情况？

import re
import os


def create_filename_for_fileout (f1):
        fileout_n = f1.replace("TT", "out")
        fileout = "C:\\Users\\KP\\Desktop\\FSC_Treetag\\out\\"+str(fileout_n)
        return fileout

for file_in in os.listdir('C:\\Users\\KP\\Desktop\\FSC_Treetag'):
    filename = str(file_in)
    file_out = create_filename_for_fileout(filename)

    open(file_in, 'r')
    open(file_out, 'w')


    content_file = file_in.readlines()
    for ln in content_file:
        regex = re.compile('(.*\t(ADJ|ADV|NOM|VER:cond|VER:futu|VER:impe|VER:impf|VER:infi|VER:pper|VER:pres|VER:pres|VER:simp|VER:subi|VER:subp)\t(.*))')
        res = regex.search(ln)
        if res:
         # categ = res.group(2)
           lemme = res.group(3)
           file_out.write(str(lemme)+"\n")

    file_out.close()    
    file_in.close()

结果：

 content_file = file_in.readlines()
AttributeError: 'str' object has no attribute 'readlines'

Answer 1

您未将$json = '{"request_list":[{"id":"1","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null},{"id":"3","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null}]}'; $data = json_decode($json ); $request = $data->request_list; foreach($request as $request_data){ echo $request_data->id; echo $request_data->name; echo $request_data->surname; }分配给任何要使用的变量。

open

Answer 2

您没有将Bitmasks = [] Bitmasks.append(int("0001", 2)) Bitmasks.append(int("0010", 2)) Bitmasks.append(int("0100", 2)) Bitmasks.append(int("1000", 2)) myNumber = 12 Bools = [] for bm in Bitmasks: Bools.append(myNumber|bm==myNumber)函数分配给相应的open（handlers正在返回文件类型的对象。）

open

应该是：

filename = str(file_in)
file_out = create_filename_for_fileout(filename)

open(file_in, 'r')
open(file_out, 'w')

注意：为了清楚起见，最好为 infile file_out = open(create_filename_for_fileout(file_in), 'w') file_in = open(file_in, 'r')使用另一个指针。

检查：https://docs.python.org/2/library/functions.html#open

open（name [，mode [，buffering]]）
handler
