Python 3 之 Chrom 截获的Headers转成dict格式

如题，直接复制Chrom截获的Headers如下：

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Encoding:gzip, deflate, sdch
Accept-Language:zh-CN,zh;q=0.8

代码如下，优快云怎么回事，第一行明明只有三个单引号，怎么发出来就变五个单引号了。

s = '''Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

'''
s = s.strip().split('\n')
s = {x.split(':')[0] : x.split(':')[1] for x in s}
print(s)

输出如下，虽然格式乱了点，但还是能用的：
