Using a single regex for finding texts having at least one occurence of a certain type

The regex rule should find texts where "MyText" is not immediately followed by a numeric character on all occurrences. So what I need is to search whether a text has at least 1 occurrence of "MyText" without being followed by a numeric. I know how to do this using 2 regexes, but I would like to use a single regex.

import re 
def find_match(s):
    g1 = re.findall("MyText", s)
    g2 = re.findall("MyText[0-9_]", s)
    if len(g1) > len(g2):
        return True
    else:
        return False

Examples:

"MyText word1 word2" ✓

"Something MyText335 blah blah blah" ⨉

"Blah blah MyText1" ⨉

"MyText something MyText02 something MyText123" ✓

>Solution :

You can use a negative lookahead 'MyText(?!\d)':

>>> re.search('MyText(?!\d)', "MyText word1 word2")
<re.Match object; span=(0, 6), match='MyText'>

>>> re.search('MyText(?!\d)', "Something MyText335 blah blah blah")
None

as a function:

import re 
def find_match(s):
    return bool(re.search('MyText(?!\d)', s))
