文件i / o问题(file i/o problem)

 我遇到一个非常简单的问题。 我正在尝试删除文件中的换行符并将输出发送到新文件。 这是我的代码： 
 
infile = open('seq.txt', mode='r', encoding='utf-8')
lines = infile.readlines()
for line in lines:
    par = line.strip('\n')

outfile = open('seqpar.txt', mode='w', encoding='utf-8')
for line in lines:
    outfile.write(par)
 
 当我运行上面的代码时，outfile（seqpar.txt）的内容是完全空白的。 我试图在线搜索I / O教程，但我似乎无法找到类似问题的任何解决方案。 由于某种原因，我在理解文件I / O时遇到了麻烦。请提前感谢您的帮助。 

I am having trouble with a really simple problem. I'm trying to remove line breaks in a file and send the output to a new file. This is my code:
 
infile = open('seq.txt', mode='r', encoding='utf-8')
lines = infile.readlines()
for line in lines:
    par = line.strip('\n')

outfile = open('seqpar.txt', mode='w', encoding='utf-8')
for line in lines:
    outfile.write(par)
 
When I run the above code, the contents of the outfile (seqpar.txt) is completely blank. I've tried to search for I/O tutorials online, but I can't seem to locate any solutions to a similar problem. I'm really having trouble with understanding file I/O for some reason.Thanks in advance for the help.
