Extracting Specific Reads From Vcf File

Hello,

I am trying to extract indels with coverage ~1 and they are in a VCF file. How do I write a python script or a shell commnad to extract those indels with coverage 1 only?

This is the data:

chr1    1548545 .       T       TAGATCG 22.5    .       INDEL;DP=2;VDB=0.0251;AF1=1;AC1=2;DP4=0,0,1,0;MQ=60;FQ=-37.5    GT:PL:GQ        1/1:60,3,0:6
