如何在案文中只发现一个白色空间的界线?
原标题:How to detect lines with only a white space in a text?

鉴于“防线”是一个白色空间:

我试图按行文读到文字档案。 我想无视白天线。 或者说更正确,我想发现空线。

空线可以包含空间、新线特征等。 这仍然被视为空线。 如果你在笔记上开张,你就不应看到任何东西。

是否在沙尔迅速这样做? 我是新到的。

最佳回答
for line in someopenfile:
  if line.isspace():
    empty_line()
问题回答

利用strip(>,介绍任何扼杀性回归,发现所有铅和拖拉的白色空间被 stripped。 因此,用一条只白天线,你空洞。 然后,你就可以在体内进行非零的过滤。

>>> lines=[     , abc ,  ]
>>> print filter(lambda x:len(x.strip()),lines)
[ abc ]
>>>
