You have successfully constructed a string without the quotes. So you need to add the double quotes. There are a few different ways to do this in Python:
您已成功构建了一个不带引号的字符串。所以你需要添加双引号。在 Python 中有几种不同的方法可以做到这一点：
>>> my_str = " ".join([a.strip() for a in b.split("\n") if a])
>>> print '"' + my_str + '"' #Use single quotes to surround the double quotes
"a b c d e f g"
>>> print "\"" + my_str + "\"" #Escape the double quotes
"a b c d e f g"
>>> print '"%s"'%my_str #Use string formatting
"a b c d e f g"
Any of these options are valid and idiomatic Python. I might go with the first option myself simply because it's short and clear
这些选项中的任何一个都是有效且惯用的 Python。我可能会自己选择第一个选项，因为它简短明了
