RE-greedy or non greedy about '?'

[frank0903]

import re
RE_QUESTION_MARK = 'yd?'
RE_ASTERISK = 'yd*'
test_str1 = 'ydddddd'
print(f'{test_str1} match result : {re.search(RE_ASTERISK, test_str1)}')
print(f'{test_str1} match result : {re.search(RE_QUESTION_MARK, test_str1)}')

Output:
ydddddd match result : <re.Match object; span=(0, 7), match='ydddddd'>
ydddddd match result : <re.Match object; span=(0, 2), match='yd'>

according to the match results, '*' is greedy, acceptable. '?' only match 0 or 1 repetitions of the preceding RE, it's non-greedy. How can we call it greedy?
