编码新手.Pytho/biopython新手; 这是我在网上的第一个问题.如何打开压缩的fasta.gz文件以提取信息并在我的函数中执行计算.这是我正在尝试做的一个简化示例(我尝试过不同的方法),以及错误是什么.我正在使用的gzip命令似乎不起作用.

with gzip.open("practicezip.fasta.gz", "r") as handle:
    for record in SeqIO.parse(handle, "fasta"):
        print(record.id)

Traceback (most recent call last):

  File "<ipython-input-192-a94ad3309a16>", line 2, in <module>
    for record in SeqIO.parse(handle, "fasta"):
