I have this code to check whether or not a variable is a number or a Vector2
:
def __mul__(self, other):
match type(other):
case int | float:
pass
case Vector2:
pass
If I run this, I get
SyntaxError: name capture 'int' makes remaining patterns unreachable
And when I hover in vscode, it gives me:
"int" is not accessed
Irrefutable pattern allowed only as the last subpattern in an "or" pattern
All subpatterns within an "or" pattern must target the same names
Missing names: "float"
Irrefutable pattern is allowed only for the last case statement
If I remove | float
it still won't work, so I can't make them separate cases.
Case with a variable (ex: case _:
or case other:
) needs to be the last case
in the list. It matches any value, where the value was not matched by a previous case, and captures that value in the variable.
A type can be used in a case, but implies isinstance()
, testing to determine if the value being matched is an instance of that type. Therefore, the value used for the match should be the actual variable other
rather than the type type(other)
, since type(other)
is a type whose type would match type()
.
def __mul__(self, other):
match other:
case int() | float():
pass
case Vector2():
pass
