Question

我有这个功能，可以从另一个文件填充自己。我很难避免以txt文件开头的标题;;;并且字典的第一个方面应该是大写的单词，后面的东西是音素。我不确定我的代码的哪一部分是错的：S

def read_file(file):
    """ (file open for reading) -> pronunciation dictionary

    Read file, which is in the format of the CMU Pronouncing
    Dictionary, and return the pronunciation dictionary.
    """
    line = file.readline()
    while line != ';;;':
        line = file.readline()
    pronun_dict = {}
    line = file.readline()
    while line != '':
        word = line.isupper()
        phoneme = line.strip()
        if phoneme not in pronun_dict:
            pronun_dict[phoneme] = [word]
        line = file.readline()
    return pronun_dict

仅当标题与“＃;;;;＆＃39;”完全匹配时，才会遇到

while line != ';;;':。我假设标头可以包含更多数据。请尝试while line.startswith(';;;'):。只要满足此条件，文件中的下一行将分配给变量line。因此，您的代码将遍历该块，直到找到不以;;;开头的行。

如何在忽略标题的同时从文件中填充字典？
