我如何获取字符串中 '\id ' 之后的第一个单词？

字符串:

python

for line in lines_in:
    if line.startswith('\id '):
        book = line.replace('\id ', '').lower().rstrip()

我得到了什么

book = 'hello some random text that can be anything'

我想要什么

book = 'hello'

一个选项:

words = line.split()
try:
    word = words[words.index("\id") + 1]
except ValueError:
    pass    # no whitespace-delimited "\id" in the string
except IndexError:
    pass    # "\id" at the end of the string
