You can match directly against the type of v, but you need a value pattern to refer to the types to match, as a "dotless" name is a capture pattern that matches any value. For example,

import builtins


values = [
    1,
    "hello",
    True
]

# Caveat: this will continue to work even if someone
# rebinds the built-in, but not, for example, if builtins.str
# itself is rebound.
for v in values:
    match type(v):
        case builtins.str:
            print("It is a string!")
        case builtins.int:
            print("It is an integer!")
        case builtins.bool:
            print("It is a boolean!")
        case _:
            print(f"It is a {type(v)}!")

Note that a value pattern must be a dotted name; it's not an arbitrary expression that can evaluate to a specific value.

(Whether you really want to match against the actual type of a value, or really want to determine if a value is an instance of a given type, is another matter. In the latter case, an if-elif statement is needed.

if isinstance(v, bool):
    print("It is a boolean!")
elif isinstance(v, int):
    print("It is an int!")
elif isinstance(v, str):
    print("It is a string!")
else:
    print(f"It is a {type(v)}!")

There is no pattern that lets you use the result of calling isinstance as the case to match against. )
