And, just for fun, since there is nothing wrong with your code, this minor
change is terser:
example = 'X - abc_degree + 1 + qq + abc_degree + 1'
for match in re.finditer(re.escape('abc_degree + 1') , example):
... print(match.start(), match.end())

Just for more fun :) -
Without knowing how general your expressions will be, I think the
following version is very readable, certainly more readable than regexes:
example = 'X - abc_degree + 1 + qq + abc_degree + 1'
KEY = 'abc_degree + 1'
for i in range(len(example)):
if example[i:].startswith(KEY):
print(i, i + len(KEY))
# prints:
4 18
26 40
If you may have variable numbers of spaces around the symbols, OTOH, the
whole situation changes and then regexes would almost certainly be the
best approach. But the regular expression strings would become harder
to read.
