从文本文件读取，而不必使用readline（）

这是我拥有的文本文件的一部分

Participant: Interviewer 
Translation: <english>Mhlongo.</english> Okay Monde, what languages do you typically use with your family and why? 
        :  
Participant: Participant 
Translation: Okay <english>it was Zulu, eh and Sotho, eh:</english> my mom is Sotho and my father is Zulu so we her language most of the time. 
        :  
Participant: Interviewer 
Translation: Mh, and so <english>you speak</english> <english>you speak</english>. What languages or language do you use with friends and why? 
        :  
Participant: Participant 
Translation:  Eh, isiZulu.

我正在尝试迭代以获取参与者和采访者的翻译。这是我的代码。

while True:
    interviewer = f.readline()
    interviewer_translation = f.readline()
    participant = f.readline()
    participant_translation = f.readline()
    ...
    if not participant_translation: break

但是，上面的代码试图逐行获取它，但是由于翻译有时要花费几行或更多行，因此无法正常工作。有没有一种方法可以不必使用readline？

浪费

如果参与者行和采访者行始终仅占一行，并且看起来始终相同，那么您可以使用类似的方法：

p_translation = ""
i_translation = ""
interviewer = False
for line in f:
    if line.startsWith("Participant: Participant"):
        #This would be the place to process i_translation
        #because now the translation of the interviewer was
        #fully read
        interviewer = False
        p_translation = ""
    elif line.startsWith("Participant: Interviewer"):
        #This would be the place to process p_translation
        #because now the translation of the participant was
        #fully read
        interviewer = True
        i_translation = ""
    else:
        if interviewer:
            i_translation += line
        else:
            p_translation += line
