Very hacky implementation of switch/case syntax for Python

switch_case.py

import types

def switch(x, *args):
    for c in args:
        if type(c.val) == types.LambdaType:
            c.val()
            if c.should_break:
                return

        elif c.matches(x):
            return c.val
    
    for c in args:
        if c.bottom == case_DEFAULT:
            return c.val

class case_DEFAULT:
    pass

class case:
    def __init__(self, bottom, top=None):
        self.bottom = bottom
        self.top = top
        self.should_break = False
    
    def matches(self, x):
        if self.top == None:
            return x == self.bottom
        
        return x >= self.bottom and x <= self.top
    
    def __call__(self, val):
        self.val = val
        return self
    
    def brk(self):
        self.should_break = True
        return self
    
def default(val):
    return case(case_DEFAULT)(val)

grade = switch(101,
    case(0, 60)(lambda: print('ur bad at school lmaoooo')).brk(),
    case(60, 69)('D'),
    case(70, 79)('C'),
    case(80, 89)('B'),
    case(90, 100)('A'),
    default('lmao')
)

print(grade)
