In Python 3.10 you can use Structural Pattern Matching
pip3 install switch_case
from switch_case import *
reason = (
switch
| case(_ == 200) >> 'OK'
| case(_ == 500) >> 'ERROR'
| default >> 'UNKNOWN')
assert reason(200) == 'OK'
assert reason(500) == 'ERROR'
assert reason(400) == 'UNKNOWN'
Which is syntax sugar for:
from switch_case import *
from operator import eq
reason = (
switch
| case(_ /eq/ 200) >> 'OK'
| case(_ /eq/ 500) >> 'ERROR'
| default >> 'UNKNOWN')
So you can use it like this:
from switch_case import *
get_type = (
switch
| case(_ /isinstance/ str) >> "string"
| case(_ /isinstance/ int) >> "integer"
| case(_ /isinstance/ float) >> "float"
| case(_ /isinstance/ bool) >> "bool"
| default >> "other")
Or as a function:
from switch_case import *
def get_type(smth):
return ~(
switch(smth)
| case(_ /isinstance/ str) >> "string"
| case(_ /isinstance/ int) >> "integer"
| case(_ /isinstance/ float) >> "float"
| case(_ /isinstance/ bool) >> "bool"
| default >> "other")
assert get_type(42) == "integer"
assert get_type("42") == "string"
assert get_type(3.14) == "float"
