finding isomiR annotation for TCGA data using API (Python)

Question

[adeline]

Hello, I'm working with the isomiR data from the TCGA database. In this dataset, I have the ref miRNA_ID eg (hsa-let-7a-1) and isoform genomic coordinate eg (hg38:chr9:94175942-94175962:+).

I'm trying to get the specific isomiR ID for each coordinate/sequence. I have already retrieved the sequence from Rest Ensembl using the genomic coordinate as query.

Now I'm looking for the isomiR ID that looks something like this: hsa-miR-145-5p.iso.t5:0.a5:0

Could anyone please suggest tools I could try? Preferably Python as I'm trying to perform this within my script.
