用python连接从文件读取的字符串？

Emacs 自动填充模式会分割行以使文档看起来更漂亮。我需要加入从文档中读取的字符串。

例如，（CR是回车符，不是真正的字符）

  - Blah, Blah, and (CR)
    Blah, Blah, Blah, (CR)
    Blah, Blah (CR)
  - A, B, C (CR) 
    Blah, Blah, Blah, (CR)
    Blah, Blah (CR)
  

使用 readlines() 函数读入字符串缓冲区数组以生成

["Blah, Blah, and Blah, Blah, Blah, Blah, Blah", "A, B, C Blah, Blah, Blah, Blah, Blah"]
  

我想过用循环来检查“-”以连接它之前的所有存储的字符串，但我希望Python有有效的方法来做到这一点。

ADDED:

根据kindall的代码，我可以得到我想要的东西，如下所示。

lines = ["- We shift our gears toward nextGen effort"," contribute the work with nextGen."]
out = [(" " if line.startswith(" ") else "\n") + line.strip() for line in lines]
print out
res = ''.join(out).split('\n')[1:]
print res

结果如下。

['\n- We shift our gears toward nextGen effort', ' contribute the work with nextGen.']
['- We shift our gears toward nextGen effort contribute the work with nextGen.']
  

当我读到它时，您的问题是撤消硬换行并将每组缩进行恢复为单个软换行。这是一种方法：

# hard-coded input, could also readlines() from a file
lines = ["- Blah, Blah, and", 
         "  Blah, Blah, Blah,",
         "  Blah, Blah",
         "- Blah, Blah, and",
         "  Blah, Blah, Blah,",
         "  Blah, Blah"]

out = [(" " if line.startswith(" ") else "\n") + line.strip() for line in lines]
out = ''.join(out)[1:].split('\n')

print out
