python如何生成textgrid文件

第一行是固定的:File type = "ooTextFile"
第二行也是固定的:Object class = "TextGrid"
空一行
xmin = xxxx.xxxx  # 表示开始时间
xmax = xxxx.xxxx  # 表示结束时间
tiers? <exists>  # 这一行固定
size = 4     # 表示这个文件有几个item, item也叫tiers, 可以翻译为'层', 这个值是几,就表示有几个item
item []:
    item [1]:
        class = "IntervalTier"
        name = "phone"
        xmin = 1358.8925
        xmax = 1422.5525
        intervals: size = 104
        intervals [1]:
            xmin = 1358.8925
            xmax = 1361.8925
            text = "sil"
        intervals [2]:
            xmin = 1361.8925
            xmax = 1362.0125
            text = "R"
        intervals [3]:
            ...
        intervals [104]:
            xmin = 1422.2325
            xmax = 1422.5525
            text = "sil"
    item [2]:
        class = "IntervalTier"
        name = "word"
        xmin = 1358.8925
        xmax = 1422.5525
        intervals: size = 3
        intervals [1]:
            xmin = 1358.8925
            xmax = 1361.8925
            text = "sp"
