Command line arguments passed to awk are stored in the internal array ARGV of ARGC elements. The first element of the array is the program name. For example:
awk 'BEGIN {
for (i = 0; i < ARGC; ++i) {
printf "ARGV[%d]=\"%s\"\n", i, ARGV[i]
}
}' arg1 arg2 arg3

# script.py
import sys
print(sys.argv[0])
print(sys.argv)
