如何使用Python搜索和替换文本从一个文件到另一个文件？
作者：互联网
我有一个文件file1.txt：
I Show more flower you can see by link
All is Beautyfull.You Can View Here !
Link View :
http://lincoln.com/view/12432134/flower1.jpg
http://lincoln.com/view/34645645/flower3456.jpg
http://lincoln.com/view/75634534/flower56.jpg
http://lincoln.com/view/86764454/flower2.jpg
还有一个file2.txt：
http://lincoln.com/view/43645645/flower1.jpg
http://lincoln.com/view/84344454/flower3456.jpg
http://lincoln.com/view/43343433/flower56.jpg
http://lincoln.com/view/13424324/flower2.jpg
http://kashi.com/view/343434344/flower1.jpg
http://kashi.com/view/766454544/flower3456.jpg
http://kashi.com/view/32634545/flower56.jpg
http://kashi.com/view/84353453/flower2.jpg
我想要的是以下内容：
I Show more flower you can see by link
All is Beautyfull.You Can View Here !
Link View :
http://lincoln.com/view/43645645/flower1.jpg
http://lincoln.com/view/84344454/flower3456.jpg
http://lincoln.com/view/43343433/flower56.jpg
http://lincoln.com/view/13424324/flower2.jpg

++++++++++++++++++++++++++++++++++++++++
I Show more candy you can see by link
All is Beautyfull.You Can View Here !
http://photobucket.com
伪代码为：
if filename exists in file1 but not in file2:
remove filename
else if filename exists in file1 and in file2:
the version in file2 replaces the line in file1
else if filename exists in file2 but not in file1:
do nothing
add the links with the domaine name "http://kashi.com" from file2.txt
in a section "More link view"
add "++++++++++++++++++++++++++"
我尝试过这种算法：
def file_merge(file1name,file2name):
file1contents = list()
file2contents = list()
file1 = open(file1name, 'U')
for line in file1:
line = line.replace('\n','')
line = line.split('/')
file1contents.append(line)
file1.close()
file2 = open(file2name, 'U')
for line in file2:
line = line.replace('\n','')
line = line.split('/')
file2contents.append(line)
file2.close()
file3contents = file1contents
for x in file2contents:
for y in file1contents:
if x[-1] == y[-1]:
file3contents[file3contents.index(y)] = x
file3 = open(file1name,'w')
for line in file3contents:
file3.write(str('/'.join(line))+'\n')
file3.close()
file_merge('file1.txt','file2.txt')
谢谢！
简单的是：
将file2.txt中的“文件名”替换为file1.txt中的“文件名”
并将链接http://kashi.com和“文件名”附加到关键字“”之前的内容中

And more content as above
解决方法:
尝试这个
import urlparse
import os
def file_merge(file1name,file2name):
file1contents = list()
file2contents = list()
file1 = open(file1name, 'U')
file1contents = file1.readlines()
file1.close()
file2 = open(file2name, 'U')
file2contents = file2.readlines()
file2.close()
file3contents = []
for link in file2contents:
temp = urlparse.urlsplit(link)
dirname, filename = os.path.split(temp.path)
file3contents.append(link)
linkin1 = False
for l_link in file1contents[4:]:
if l_link.endswith(filename):
linkin1 = True
if not linkin1:
urllist = list(temp)
urllist[1] = 'kashi.com'
file3contents[-1] = urlparse.urlunsplit(urllist)
file3 = open(file1name,'w')
for line in file3contents:
file3.write(line)
file3.close()
file_merge('/tmp/file1.txt','/tmp/file2.txt')
