#Date Bool
def isDate(string):
    elem = []
    splits = string.split()
    for element in splits:
        elem.append(element)
    if len(elem) > 5:
        return True if elem[2].isdigit() else False
    else:
        return False

#LOAD HANDLER
def loader(file):
    lines = []
    with open(file,encoding='utf8') as f:
        for line in f:
            lines.append(line)
    return lines

class define:
    def __init__(self, date, token, tweet):
            self.date = date
            self.token = token
            self.tweet = tweet

理论

所以我的想法是根据该行的第一个元素是否是日期进行拆分，并且函数 isdate() 执行此操作，但我不确定如何将前一个元素附加到当前元素以便加入项目?不知道这有多好理解，但我试图说明它：

所以在这个片段中，我们看到推文有多行，我需要一种方法将这两行连接在一起，以便我可以对其进行操作。因此，如果加入，这将类似于：

['Tue Feb 04 12:36:05 EST 2020|@Iam_Adrii|RT @iRealPedro: PUBLIC @TANNEDja ANNOUNCEMENT The Road Marshall speaks ‼️⚠️‼️ [LINK]']

没有 \n 或类似的，所以我不确定如何继续。最终我会将其放入字典中，但我需要先弄清楚基本原理。

【问题讨论】：

难道我们看到这条推文有多行和没有\n或类似的相互矛盾吗？你能澄清一下吗？

【解决方案1】：

我建议首先像这样重写你的函数：

def isDate(string):
    splits = string.split(maxsplit=3)
    return len(splits) > 3 and splits[2].isdigit()

然后以这种方式使用它：

def loader(file):
    lines = []
    with open(file,encoding='utf8') as f:
        for line_with_newline in f:
            line = line_with_newline.rstrip()
            if isDate(line):
                lines.append(line)
            else:
                lines[-1] += line
    return lines
