Hello. my university give me a zip file that contain VCF and its tbi So, I have one VCF file that contains many variants for many person. and tbi that I didn't open it until now.

I want to create a simple genotype matrix genotype matrix consists of row and columns of course which the row is define the person and the columns is ID of variants
then I fill row/column with the ref columns that related to it. All information I found it in VCF expect person.

So, from where can I extract the person info such as id so I know this info related to this id? and how???? also where can I use tbi file?

I'm using linux and python

Thank you very much
