Example
from functools import singledispatch
@singledispatch
def process(arg):
print(f"Generic: {arg}")
@process.register(int)
def _(arg):
print(f"Integer: {arg * 2}")
@process.register(str)
def _(arg):
print(f"String: {arg.upper()}")
process(5) # Integer: 10
process("hi") # String: HI Pro Tip
singledispatch only dispatches on the first argument type.
