Try this:
尝试这个：
print l.replace('"','\"')
'\"'doesn't mean anything special to Python, so you needn't to add \before ",if you run
'\"'对 Python 没有什么特别的意义，所以你不需要\在之前添加"，如果你运行
print l.replace('\"', '\\"'),you will get a single backslash too.
print l.replace('\"', '\\"'), 你也会得到一个反斜杠。
Actually what you are seeing is the representation of the string, it's added by repr()method.Python represents backslashes in strings as \\because the backslash is an Escape Character.
实际上你看到的是字符串的表示，它是通过repr() 方法添加的。Python表示字符串中\\的反斜杠，因为反斜杠是一个转义字符。
If you print it, you will get single backslash.
如果你打印它，你会得到一个反斜杠。
You can see more information from String and Bytes literals.
