使用文本文件查找特定短语后的单词，直到不同的短语

Question

有没有办法找到某个短语，然后使用以下信息（仅在它之后）作为输出，但只能使用不同的指定短语？抱歉，如果它令人困惑！

Answer 1

例如：

string = "Is there a way to find a certain phrase, " \
         "then use the following information (only after it) " \
         "as an output, but only up until a different " \
         "specified phrase? sorry if its confusing!"
first_phrase = "certain phrase"
second_phrase = "a different specified phrase"

intermediate = (string[string.find(first_phrase)+len(first_phrase):])
final = intermediate[0:intermediate.find(second_phrase)]

print final

最终结果是：

, then use the following information (only after it) as an output, but only up until 

这是你想要的。你可以重构代码来摆脱中间变量，但我想让它可读。
