清理推文，没有显示任何内容-Java 学习之路

我正在尝试运行下面的代码来清理txt文件中的一组推文

我也在命令行中定义了参数，但似乎没有输出

知道我可能做错了吗？

以下是代码：

码：

#!/usr/bin/python
# -*- coding: utf-8 -*-

import sys
import os
import re
import string
from nltk.corpus import stopwords
from nltk import word_tokenize
from nltk import pos_tag


def clean(path, filename):

    # print("Cleaning "+path)

    filename = CLEANED_DATA + filename.strip()
    WRITE_HANDLER = open(filename, 'wb')
    tweets = dict()
    for line in open('/Users/Mustafa/Desktop/nexalogy/project3.txt',
                 'rb'):
        line = re.sub(r'[.,"!]+', '', line, flags=re.MULTILINE)  # removes the characters specified
        line = re.sub(r'^RT[\s]+', '', line, flags=re.MULTILINE)  # removes RT
        line = re.sub(r'https?:\/\/.*[\r\n]*', '', line,
                  flags=re.MULTILINE)  # remove link
        line = re.sub(r'[:]+', '', line, flags=re.MULTILINE)
        line = filter(lambda x: x in string.printable, line)  # filter non-ascii characers

        new_line = ''
        for i in line.split():  # remove @ and #words, punctuataion
            if not i.startswith('@') and not i.startswith('#') and i \
                not in string.punctuation:
                new_line += i + ' '
        line = new_line

        # # Do sentence correction

        if new_line in tweets:
            continue
        else:
            tweets[new_line] = 1
        if len(new_line.strip()) > 0:
           WRITE_HANDLER.write(new_line + '''

''')
    return filename


DATA_FOLDER = sys.argv[1]
CLEANED_DATA = sys.argv[2]
for (root, dirs, files) in os.walk(DATA_FOLDER):  # gets all the files from 
subfolders recrsively
    for name in files:
        absolute_path = os.path.join(root, name)
        if os.path.isfile(absolute_path) and name != '.DS_Store':
        filename = clean(absolute_path, name)

文件：Project3.txt

这是一个完全正常的版本：

#!/usr/bin/python
# -*- coding: utf-8 -*-

import sys
import os
import re
import string

def clean(inputDir, outputFile):

    # print("Cleaning "+path)

    WRITE_HANDLER = open(outputFile, 'wb')
    tweets = dict()
    for line in open(inputDir + './project3.json','rb'):
        # print "Before" + line
        line = re.sub(r'[.,"!]+', '', line, flags=re.MULTILINE)  # removes the characters specified
        line = re.sub(r'^RT[\s]+', '', line, flags=re.MULTILINE)  # removes RT
        line = re.sub(r'https?:\/\/.*[\r\n]*', '', line, flags=re.MULTILINE)  # remove link
        line = re.sub(r'[:]+', '', line, flags=re.MULTILINE)
        line = filter(lambda x: x in string.printable, line)  # filter non-ascii characers

        new_line = ''
        for i in line.split():  # remove @ and #words, punctuataion
            if not i.startswith('@') and not i.startswith('#') and i not in string.punctuation:
                new_line += i + ' '
        line = new_line

        # # Do sentence correction

        if new_line in tweets:
            continue
        else:
            tweets[new_line] = 1
        if len(new_line.strip()) > 0:
            #print  "Writing new line"
            WRITE_HANDLER.write(new_line + '''''')
    return outputFile


DATA_FOLDER = sys.argv[1]
CLEANED_DATA = sys.argv[2]
clean(DATA_FOLDER, CLEANED_DATA)

你通过以下方式调用它：

python clean.py inputDirectory outputFileName

您的代码存在一些问题：

您正在对'for line in open'语句中的输入文件进行硬编码
您的输出文件名不会是clean.txt . 它将是clean.txt，clean.txt ...将为您的目录中的每个文件创建一个
有一些奇怪的缩进
您发布的JSON全部在一行上，因此被删除标点符号的语句删除了
您正在传递文件名，但是尝试根据该文件名来运行os文件系统 . 你应该通过：

python clean.py DIR_NAME CLEAN_FILE

在修复缩进并美化JSON之后，我得到了正确的输出：

def clean(path, filename):

    # print("Cleaning "+path)

    filename = CLEANED_DATA + filename.strip()
    print filename
    WRITE_HANDLER = open(filename, 'wb')
    tweets = dict()
    for line in open('./project3.json','rb'):
        # print "Before" + line
        line = re.sub(r'[.,"!]+', '', line, flags=re.MULTILINE)  # removes the characters specified
        line = re.sub(r'^RT[\s]+', '', line, flags=re.MULTILINE)  # removes RT
        line = re.sub(r'https?:\/\/.*[\r\n]*', '', line, flags=re.MULTILINE)  # remove link
        line = re.sub(r'[:]+', '', line, flags=re.MULTILINE)
        line = filter(lambda x: x in string.printable, line)  # filter non-ascii characers

        new_line = ''
        for i in line.split():  # remove @ and #words, punctuataion
            if not i.startswith('@') and not i.startswith('#') and i not in string.punctuation:
                new_line += i + ' '
        line = new_line

        # # Do sentence correction

        if new_line in tweets:
            continue
        else:
            tweets[new_line] = 1
        if len(new_line.strip()) > 0:
            #print  "Writing new line"
            WRITE_HANDLER.write(new_line + '''''')
    return filename
