Both {foo} and $foo work for using variables from Python code, but you
will need to double them up where you want to pass {, } or $ to the
command. Try this:

!awk '{{print $$1}}'
'/home/ckivip/Epigenetics/Data/H1hesc/Dnamethy.bed' >

(The email splits it over three lines, but it should go all on one line)
