dict.get(key, default) evaluates default even if key exists

[Paul Bryan]

Maybe this will help:

>>> def get(key, default):
...   print("entering get")
...   print(f"{key=} {default=}")
...   print("exiting get")
... 
>>> def generate_default():
...   print("entering generate_default")
...   print("exiting generate_default")
...   return 1
... 
>>> get("a", generate_default())
entering generate_default
exiting generate_default
entering get
key='a' default=1
exiting get
>>>
