Python的行结束 ''

Question

此代码

with open('iter.txt') as f: 
    try: 
     while True: 
      line = next(f) 
      print(line,end='') 
    except StopIteration: 
      pass 

按预期工作。 但与

print(line,end='\n') 

插入空行。

Iteration is one of Python’s strongest features. At a high level, you might simply view 

iteration as a way to process items in a sequence. However, there is so much more that 

is possible, such as creating your own iterator objects, 

为什么？ os.linesep有没有其他选择？

Answer 1

据我所知，如果只有你的行不以它结束才能防止这个额外的空行，你要打印一个新行符号（os.linesep）。

它可以与这样的检查来解决：

import os 


with open('iter.txt') as f: 
    for line in f: 
     # Print with end='' if your line contains a new line 
     # Otherwise, print this new line 

     linesep = os.linesep 
     line_end = '' if linesep in line else linesep 

     print(line, end=line_end)
