splitlines() 方法

一、splitlines() 方法

splitlines() 方法将字符串拆分为列表，拆分在换行符处完成。
以行为单位存成列表

txt = "Thank you for the music\nWelcome to the jungle"

x = txt.splitlines()

print(x)

['Thank you for the music', 'Welcome to the jungle']

把文本全读进来，这样才可以对每一行进行拆解

        with open(path, "r") as f:
            #Python splitlines() 按照行('\r', '\r\n', \n')分隔
            labels = f.read().splitlines()
        if "O" not in labels:
            labels = ["O"] + labels
        return labels
