[英]How to create python executable from a .py file that need to read and write .txt files in a separate folder
[英]python read all files from a folder and write the file name and other info into a txt file
我有30911个html文件。 我需要进行网络抓取,然后将信息保存到名为index.txt的txt文件中。 它看起来像
filename1, title, t1, date, p1
filename2, title, t1, date, p1
filename3, title, t1, date, p2
and so on...
我只想要文件名,但是输出给了我path + filename。
您可以使用:
path = 'C:/Users/.../.../output/'
#read html files
for filename in glob.glob(os.path.join(path, '*.html')):
soup = bs4.BeautifulSoup(open(filename).read(), "lxml")
title = soup.find('h1')
ticker = soup.find('p')
d_date = soup.find_all('div', {"id": "a-body"})[0].find_all("p")[2]
try:
def find_participant(tag):
return tag.name == 'p' and tag.find("strong", text=re.compile(r"Executives|Corporate Participants"))
participants = soup.find(find_participant)
parti_names = ""
for parti in participants.find_next_siblings("p"):
if parti.find("strong", text=re.compile(r"(Operator)")):
break
parti_names += parti.get_text(strip=True) + ","
except:
indexFile = open('C:/Users/.../output1/' + 'index.txt', 'a+')
indexFile.write(filename + ', ' + title.get_text(strip=True) + ', '+ ticker.get_text(strip=True) + ', ' + d_date.get_text(strip=True) + ', ' + 'No participants' + '\n')
else:
participants = soup.find(find_participant)
parti_names = ""
for parti in participants.find_next_siblings("p"):
if parti.find("strong", text=re.compile(r"(Operator)")):
break
parti_names += parti.get_text(strip=True) + ","
indexFile = open('C:/Users/.../output1/' + 'index.txt', 'a+')
indexFile.write(os.path.basename(filename) + ', ' + title.get_text(strip=True) + ', '+ ticker.get_text(strip=True) + ', ' + d_date.get_text(strip=True) + ', ' + parti_names + '\n')
indexFile.close()
您的问题是文件名实际上是文件路径,为了获得文件名,您可以使用os模块
os.path.basename('filepath')
因此,为了写入文件:
indexFile.write(os.path.basename(filename)+ ', ' + title.get_text(strip=True) + ', '+ ticker.get_text(strip=True) + ', ' + d_date.get_text(strip=True) + ', ' + parti_names + '\n')
ntpath
是另一个用于从路径获取基本名称的模块。
>>> import ntpath
>>> ntpath.basename('C:/Users/.../output1/' + 'index.txt')
'index.txt'
