Python3: 使用 Dateutil 从一个长字符串中生成多个变量
Python3: Use Dateutil to make multiple vars from a long string
我有一个程序，我想从一首歌中随机抽出一行，然后将它们与其他歌曲的其他歌词串在一起。通过查看，我发现 dateutil 库可能能够帮助我从一个字符串中解析多个变量，但它并没有完全满足我的要求。
我有多个这样的字符串，只是更长。
"This is the day\nOf the expanding man\nThat shape is my shade\nThere where I used to stand\nIt seems like only yesterday\nI gazed through the glass\n..."
我想从这个字符串中随机拉出一行（到分页符）并将其保存为一个变量，但是在多个字符串上迭代它，任何帮助将不胜感激。
假设您想从字符串中随机抽取一行，您可以使用 random 模块中的 choice。
random. choice ( seq ): Return a random element from the non-empty
sequence seq. If seq is empty, raises IndexError.
from random import choice
data = "This is the day\nOf the expanding man\nThat shape is my shade\nThere where I used to stand\nIt seems like only yesterday\nI gazed through the glass\n..."
my_lines = data.splitlines()
my_line = choice(my_lines)
print(my_line)
输出
That shape is my shade
