Answer to Question #100344 in Python for AVEMARIA P. J. GOGWIM

Question

• Create your own example of each possibility in Python code. List the code for each example, along with sample output from trying to run it.

Answer 1

Preconditions - A precondition decorator utility which relies on parameter-name equivalence for conciseness and consistency.

from preconditions import preconditions
@preconditions(lambda i: isinstance(i, int))
def triple(i):
    return 3*i

triple(5) in console will return 15, but triple(5,1)v will give an error, because of violating preconditions.

Postconditions do same, but for output arguments, not for input.

All standard Python functions, with examples of code:
