问Python3值:TypeError必须是字符串或字节的实例，而不是元组EN通过学习，我们知道这个RcisTarget包内置的motifAnnotations_hgnc是16万行，可以看到每个基因有多个motif。而且下载好的 hg19-tss-centered-10kb-7species.mc9nr.feather 文件，也是 24453个motifs的基因排序信息。但是我们留下来了一个悬念，如何从几万个注释...

I would understand the unorderable types error - after all, I'm asking to have different types in the index, and pandas maybe wants to compare them, and it can't (this error obviously only affects Python3). But then, In [3]: pd.DataFrame([[2, 'a'], [4, (1,2)]]).set_index...

Mypy will flag this example with the error message Cannot inherit from final class "Base". To learn more about Final and @final, see PEP 591.The third PEP allowing for more specific type hints is PEP 589, which introduces TypedDict. This can be used to specify types for keys and values...
