title: Global variables in Snakemake rules
body: <p>I'm creating a simple snakemake pipeline that contains global variables in the Snakefile. What's the recommended way to use these global variables in the Python scripts called in my rules?</p>
  <p>I'm currently using argparse command line arguments as described here (<a href="https://stackoverflow.com/questions/61370077/snakemake-pass-command-line-arguments-to-scripts">Snakemake: pass command line arguments to scripts</a>) but am wondering if there's a better way.</p>
