Assertion with a command

Is there a way to pass a function into the string portion of an 'assert' statement like below? If not, are there any keywords in which I can do so?

f=5  
def something():
    assert f!=5, do_something_else()

assert is used for Testing Warnings and you shouldn't rely on it for executing a block of codes. official documentation

You can put a function call in an assert statement just as you showed. The function doesn't even have to return a string. Python will try to put out a readable representation of whatever the function returns, including None.

The function will only be called if the condition after assert is false.

You can use an if statement for this:

f = 5
def something():
    if f!= 5:
        do_something_else()
