[Solved] Regex behaving weird when finding floating point strings [duplicate]

As you guessed correctly, this has to do with capturing groups. According to the documentation for re.findall:

If one or more groups are present in the pattern, return a list of groups

Therefore, you need to make all your groups () non-capturing using the (?:) specifier. If there are no captured groups, it will return the entire match:

>>> pattern = r'(?:\d*\.)?\d+'

>>> findall(pattern, s)
['7.95', '10']
