for each_line in f: #为什么可以以每行为单位遍历,而不是每个字符遍历
if each_line[:6] != '======':
(role, line_spoken) = each_line.split(':', 1) #这里的1是什么意思
if role == '小甲鱼':
boy.append(line_spoken)

======================
问题在程序的批注中,我学的是Python3,用的是win7
这个仅对一行而言,for将每行读成一个字符串。
比较一下下面两个的差异。
- >>> 'abc:def:123'.split(':')
- ['abc', 'def', '123']
- >>> 'abc:def:123'.split(':', 1)
- ['abc', 'def:123']
