(Desired) program takes a .bed file compresses it, reconverts the gzipped file to a .txt file , and then reads the contents and produces individual gzipped .bed files for each chromosome containing each gene belonging to that chromosome. vs. (Reality) the current script produces gzipped files for every gene for each chromosome and then eventually throws an error

FileNotFoundError: [Errno 2] No such file or directory: example_by_chrom.chr12,11733136,11733137,Cyp3a23/3a1,1,-.bed.gz'

Any help with solving this problem will be greatly appreciated. I have been stuck for days with this issue.
