Multiple variable inputs when only one is called for

[ChrisDall]

Hi all, trying to run a python code (not mine) that used a function generate_index(arg). The arg function is actually meant to have 5 parts (host, graft, index, memory, and threads) and these components are called later in the function as arg.host, arg.graft...etc.

Probably a dumb question, but how can i input these five variables into the function? when I separate by commas, i get an error saying only expected one variable. I tried adding a double asterisk to before the variable arg, but this did not help either...

Relevant introduction to the Code as below and is from the xenocell repository:

def generate_index(**args):

  print_header(args)
  print_log('Generate index...')
  create_directory(args.output)
  run_xenome(args)
  print_log('Generation of Xenome index finished!')


#
def print_header(args):
  header = '''##----------------------------------------------------------------------------##
## XenoCell: Generate Xenome index of reference genomes.
##----------------------------------------------------------------------------##
## FASTA of host reference genome:  {host}
## FASTA of graft reference genome: {graft}
## Output directory:                {output}
## Number of threads:               {threads}
## Memory in GB:                    {memory}
##----------------------------------------------------------------------------##'''.format(
    host    = args.host,
    graft   = args.graft,
    output  = args.output,
    threads = args.threads,
    memory  = args.memory
