You can simply use the guard feature along with capture:
>>>my_str = "iwill/predict_something"
>>>match my_str:
... case str(x) if 'predict' in x:
... print("match!")
... case _:
... print("nah, dog")
...
match!

Python Compare Strings - Methods & Best Practices | DigitalOcean
April 17, 2025 - In this article, you’ll learn how each of the operators work when comparing strings. Python string comparison compares the characters in both strings one by one. When different characters are found, then their Unicode code point values are compared.

subprocess — Subprocess management
On POSIX with shell=True, the shell defaults to /bin/sh. If args is a string, the string specifies the command to execute through the shell. This means that the string must be formatted exactly as it would be when typed at the shell prompt.

You could use the [*_] wildcard sequence capture pattern: https://peps.python.org/pep-0622/#sequence-patterns
def is_holiday(yourstring: str):
match yourstring.split():
case [*_, "holidays"]:
return True
case [*_, "workday"]:
return False
print(is_holiday("xmas holidays"))

re — Regular expression operations
3 days ago - Group names must be valid Python identifiers, and in bytes patterns they can only contain bytes in the ASCII range. Each group name must be defined only once within a regular expression. A symbolic group is also a numbered group, just as if the group were not named. Named groups can be referenced in three contexts. If the pattern is (?P<quote>['"]).*?(?P=quote) (i.e. matching a string quoted with either single or double quotes):

The == operator is a simple way to check if two strings are identical. If both strings are equal, it returns True; otherwise, it returns False. ... s1 = "Python" s2 = "Python" # Since both strings are identical, therefore it is True print(s1 == s2)

January 30, 2025 - If value is 10, the value will be compared with case 10 and it will print "Ten". If value is 20, it will print "Twenty". For any other value, it will print "Something else". The underscore (_) acts as a wildcard, catching any case that isn't explicitly matched.

Are you sure you need a regex? It seems that you only need to know if a word is present in a string, so you can do:
>>> line = 'This,is,a,sample,string'
>>> "sample" in line
True

The r makes the string a raw string, which doesn't process escape characters (however, since there are none in the string, it is actually not needed here).
Also, re.match matches from the beginning of the string. In other words, it looks for an exact match between the string and the pattern. To match stuff that could be anywhere in the string, use re.search. See a demonstration below:
>>> import re
>>> line = 'This,is,a,sample,string'
>>> re.match("sample", line)
>>> re.search("sample", line)

F-strings are not allowed (since in general they are not really literals). ... Only a single name is allowed (a dotted name is a constant value pattern). A capture pattern always succeeds. A capture pattern appearing in a scope makes the name local to that scope. For example, using name after the above snippet may raise UnboundLocalError rather than NameError, if the "" case clause was taken: match greeting: case "": print("Hello!") case name: print(f"Hi {name}!") if name == "Santa": # <-- might raise UnboundLocalError ...

Like the python-Levenshtein library, it also has a ratio function: from fuzzywuzzy import fuzz str1 = 'But I have promises to keep, and miles to go before I sleep.' str2 = 'But I have many promises to keep, and miles to run before sleep.' ratio = fuzz.ratio(str1, str2) The library also provides advanced functions for handling other complex string matching scenarios.
