Answer 1

For me the easiest way to circumvent all the command line quoting problems is to write the code to a file with GNUmake's $(file ) function. You can even use # as Python comment inside of defined variables:

VERSION := $(shell bash --version)

# With this, you can use any form of quotes inside your python code
define PYTHON_VERSION_CODE :=
# -*- coding: iso-8859-15 -*-
import re, sys;
program_version = "${VERSION}"
match = re.search("Copyright[^\d]+(\d+)", program_version);

if match:
    if int( match.group(1) ) >= 2018:
        sys.stdout.write("1")
    else:
        sys.stdout.write( "match:" + match.group(1) )
else:
    sys.stdout.write("0")
endef


$(file > test.py,$(PYTHON_VERSION_CODE))

PYTHON_SCRIPT_RESULTS := $(shell python test.py)

.PHONY: all
all:
    @echo $(PYTHON_SCRIPT_RESULTS)
