I haven't tested it either but it looks like it would work. But for this case
I prefer the relative simplicity of:
example = 'X - abc_degree + 1 + qq + abc_degree + 1'
find_string = re.escape('abc_degree + 1')
for match in re.finditer(find_string, example):
print(match.start(), match.end())
4 18
26 40
I don't insist on terseness for its own sake, but it's cleaner this way.
