When a function/method has arguments with a default value assigned all other callers of the function/method should explicitly specify the optional argument name.
def foo(bar=None, zoo=None):
pass
Bad:
foo(1, "lion")
Good:
foo(bar=1, zoo="lion")
Rationale:
Additional optional arguments will likely be added to the function/method in the future and the callers won't need to be hunted down and updated to account for the new optional argument added.
Example:
def foo(flag=True, bar=None, zoo=None):
pass
Bad:
foo(1, "lion") # unexpected result since flag is now assigned 1 and bar is now assigned "lion"
Good:
foo(bar=1, zoo="lion") # No change necessary - behaves the same as before
