python合并成txt

Ⅰ python中将两个文件合并

你好：

其实这个问题不是很难啊：

请看代码：

txtpath1=r"a.txt"
txtpath2=r"b.txt"
txtpath3=r"c.txt"

fpa=open(txtpath1)
fpb=open(txtpath2)
fpc=open(txtpath3,"w")

arrB=[]
forlinebinfpb.readlines():
arrB.append(lineb)

index=0
forlineainfpa.readlines():
index=index+1
fpc.write(linea)
foriinrange((index-1)*10,(index)*10):
try:
fpc.write(arrB[i])
except:
pass
print"Done!"
fpa.close()
fpb.close()
fpc.close()

Ⅱ 用Python 将两个文件的内容合并成一个新的文件.

f1 = open("mit.txt", 'a+')
f2 = open("unitcode.txt",'r')
f3 = open("unitname.txt",'r')
s2 = f2.read().replace('\n', '').split(',')
s3 = f3.read().replace('\n', '').split(',')
f1.write('Unit name\tUnit Codes\n')
for i1, i2 in zip(s2, s3):
f1.write("%s\t%s\n" % (i1.strip(), i2.strip()))
f1.close()
f2.close()
f3.close()

如果就是想让格式对的很齐的化，只要格式化输出就行了。用ljust的函数对齐就行了。

Ⅲ Python 读取文档各行中同一列数据并按首尾相接合并输出到另一个文件中

def_556225095(infile,outfile):
reader=open(infile,'r')
writer=open(outfile,'w')
buff=[]
buff_size=1000#文件太大，分块缓存输出
whileTrue:
line=reader.readline()
iflen(line)==0:
break
field=line.split()[2]
buff.append(field.strip())
iflen(buff)>=buff_size:
writer.write(''.join(buff))
buff=[]
else:
writer.write(''.join(buff))
writer.close()
reader.close()

Ⅳ 求一个python3爬虫代码，可以从小说网站上直接把小说的文字抄下来，并整合到一个新的文本里

frombs4importBeautifulSoup
fromrequests.
importre
importrequests
importos

defget_html_text(url):
try:
r=requests.get(url)
r.raise_for_status()
returnr.text
exceptRequestException:
returnNone

defget_chapter_names(html):
soup=BeautifulSoup(html,'lxml')
charpter=soup.select('.bg')
charpter_names=[]
forentryincharpter[1:]:
charpter_name=re.findall('<h2>(.*?)</h2>',str(entry))
file_name=re.findall('<ahref.*?>(.*?)</a>',str(entry))
ifcharpter_nameandfile_name:
fornameinfile_name:
name=name.split('')[0]
charpter_names.append(charpter_name[0]+'_'+name)
else:
pass
returnset(charpter_names)

defget_each_url(html):
soup=BeautifulSoup(html,'lxml')
urls=soup.select('ullia')
forurlinurls:
link=url.get('href')
text=url.text.split('')[0]
full_name=url.text.replace('?','')
yield{'url':link,'text':text,'full_name':full_name}
print(text)

defget_text(url):
r=requests.get(url)
r.encoding=r.apparent_encoding
soup=BeautifulSoup(r.text,'lxml')
items=soup.select('div.content-body')
item=re.findall(';(.*?);',items[0].text,re.S)
returnitem[0].encode()

defsave_to_file(url,text,full_name):
base_dir='mu'
path='{}\{}\{}'.format(os.getcwd(),base_dir,text)
ifnotos.path.exists(path):
try:
os.makedirs(path)
except:
pass
try:
withopen(path+'\'+full_name+'.txt','wb')asf:
f.write(get_text(url))
except:
pass

defmain():
url='http://seputu.com/'
html=get_html_text(url)
chapters=get_chapter_names(html)
forchapterinchapters:
foreachinget_each_url(html):
ifeach['text']==chapter.split('_')[-1]:
save_to_file(each['url'],chapter,each['full_name'])

if__name__=='__main__':
main()

Ⅳ python 如何把多个文件内容合并到以一个文件

Python编程将多个文件合并，代码如下：

#例子：合并a.txt、b.txt、c.txt合并成d.txt文件

#文件列表，遍于读取

flist = ['a.txt','b.txt','c.txt']

#要写入的文件

ofile = open('d.txt', 'w')

#遍历读取所有文件，并写入到输出文件

for fr in flist:
for txt in open(fr, 'r'):
ofile.write(txt)
ofile.close()
效果如下：
