Python recently has released match-case in version 3.10. The question is how can we do a default case in Python? I can do if/elif but don't know how to do else. Below is the code:
x = "hello"
match x:
case "hi":
print(x)
case "hey":
print(x)
default:
print("not matched")
I added this default myself. I want to know the method to do this in Python.
You can define a default case in Python. For this you use a wild card (_). The following code demonstrates it:
x = "hello"
match x:
case "hi":
print(x)
case "hey":
print(x)
case _:
print("not matched")
match subject:
case <pattern_1>:
<action_1>
case <pattern_2>:
<action_2>
case <pattern_3>:
<action_3>
case _:
<action_wildcard>
cf: https://docs.python.org/3.10/whatsnew/3.10.html#syntax-and-operations
for thing in [[1,2],[2,11],[12,14,13],[10],[10,20,30,40,50]]:
match thing:
case [x]:
print(f"single value: {x}")
case [x,y]:
print(f"two values: {x} and {y}")
case [x,y,z]:
print(f"three values: {x}, {y} and {z}")
case _: # change this in default
print("too many values")
