Another option (I cheated a little and turned sInput into a sequence
of lines, similar to what you would get reading a text file):
sInput = [
'; $1 test1',
' ; test2 $2',
' test3 ; $3 $3 $3',
'test4',
'$5 test5',
' $6',
' test7 $7 test7',
]
import re
re_exp = re.compile(r'(\$.)')
re_cmt = re.compile(r'\s*;')
expansions = [exp for line in sInput for exp in re_exp.findall(line)
if not re_cmt.match(line)]
print(expansions)
>>> ['$3', '$3', '$3', '$5', '$6', '$7']
